1. The highest winning percentage (Win%) comes from horses that finished first (5%) in their previous race, followed by those that finished second (4%), fifth (4%), and ninth (3%).
2. Horses that finished first in their previous race also have the highest Place% (20%), followed by those that finished eighth (17%), fifth (15%), and second (14%).
3. The most profitable past performance in terms of Profit/Loss (P/L) is finishing eighth, with a P/L of 65. This is followed by those that finished fifth (P/L of 19) and ninth (P/L of 12).
4. Horses that pulled up in their previous race have the lowest winning percentage (1%) and one of the lowest place percentages (5%).

Based on these trends, we can conclude that horses that finished in the top three in their previous race, particularly those that finished first, have a higher likelihood of winning or placing in the Grand National.

1. The highest winning percentage (Win%) is shared by horses aged 9, 10, and 11, all with a 3% win rate. Horses aged 8 come in a close second with a 2% win rate.
2. Horses aged 11 have the highest place percentage (Place%) at 12%, followed by horses aged 8 and 9 with a 14% and 12% place rate, respectively.
3. In terms of Profit/Loss (P/L), horses aged 7 and 11 have positive P/L values, with P/L of 2 and 3 respectively. All other age groups show a negative P/L.
4. Younger horses (aged 6) and older horses (aged 13 and 14) have significantly lower win rates (0%) and place rates (0-9%).

Based on these trends, we can conclude that horses aged 8 to 11 have a higher likelihood of winning or placing in the Grand National, with horses aged 11 showing slightly better profitability.

1. Horses with an official rating of 139 have the highest winning percentage (Win%) at 11%, followed by those with ratings of 159 and 160, both at 13%. However, horses with ratings of 159 and 160 have significantly fewer runs, so their win rates may not be as reliable.
2. The highest place percentage (Place%) is shared by horses with ratings of 159 and 160 (38%), followed by those with ratings of 150 (17%) and 138 (17%).
3. The most profitable past performance in terms of Profit/Loss (P/L) is an official rating of 148, with a P/L of 110. This is followed by horses with ratings of 157 (P/L of 20), 160 (P/L of 18), and 138 (P/L of 22).
4. Horses with official ratings between 127 and 135 show consistently poor results, with a 0% win rate and low place percentages.

Based on these trends, we can conclude that horses with official ratings between 138 and 160 have a higher likelihood of winning or placing in the Grand National, particularly those with ratings of 139, 148, 159, and 160. Horses with ratings of 148, 157, 160, and 138 also show better profitability.

Based on the provided statistics of past Grand National winners in relation to the days since their last run, we can observe the following trends:

1. The highest winning percentage (Win%) is shared by horses that last raced 16-30 days (C) and 31-60 days (D) ago, both with a 3% win rate.
2. The highest place percentage (Place%) is found among horses that last raced 16-30 days (C) ago, with an 11% place rate. This is followed by those that last raced 31-60 days (D) ago with a 10% place rate.
3. In terms of Profit/Loss (P/L), all categories show a negative P/L. However, the least negative P/L is found in horses that last raced 16-30 days (C) ago, with a P/L of -85. This is followed by horses that last raced 31-60 days (D) ago with a P/L of -103.
4. Horses that have either raced very recently (1-15 days ago, categories A and B) or not raced in a long time (over 120 days ago, categories F, G, and H) show lower win rates (0-2%) and place rates (0-13%).

Based on these trends, we can conclude that horses that last raced between 16 and 60 days ago (categories C and D) have a higher likelihood of winning or placing in the Grand National.

1. The highest winning percentage (Win%) is in the 5/2 & 4/1 odds bracket (E), with a 100% win rate. However, this is based on just one run, so it’s not a reliable indicator.
2. The next highest win rates are found in the 13/2 & 8/1 odds bracket (G) with a 9% win rate, followed by the 17/2 & 12/1 odds bracket (H) with a 7% win rate.
3. The highest place percentage (Place%) is found in the 13/2 & 8/1 odds bracket (G), with a 41% place rate, followed by the 17/2 & 12/1 odds bracket (H) with a 22% place rate.
4. In terms of Profit/Loss (P/L), the most profitable odds bracket is the 5/2 & 4/1 odds bracket (E), with a P/L of 4, but again, this is based on just one run. The next least negative P/L is found in the 13/2 & 8/1 odds bracket (G) with a P/L of -10, followed by the 17/2 & 12/1 odds bracket (H) with a P/L of -22.
5. Horses with odds of 50-1 or above (K) have a significantly lower win rate (1%) and place rate (3%).

Based on these trends, we can conclude that horses with odds between 13/2 and 12/1 (odds brackets G and H) have a higher likelihood of winning or placing in the Grand National. These odds brackets also show relatively better profitability.

1. The highest winning percentage (Win%) is found in the 11-5 weight bracket, with an 8% win rate, followed by the 11-0 weight bracket, with a 7% win rate.
2. The highest place percentage (Place%) is found in the 10-1 weight bracket, with a 23% place rate, followed by the 10-11 weight bracket, with a 17% place rate.
3. In terms of Profit/Loss (P/L), the most profitable weight bracket is the 11-0 weight bracket, with a P/L of 86. This is followed by the 10-10 weight bracket, with a P/L of 19.
4. Horses with a weight of 10-0 to 12-0 have a range of winning percentages between 0% and 8%. The majority of these brackets have win rates between 2% and 4%.

Based on these trends, we can conclude that horses with weights between 11-0 and 11-5 (inclusive) have a higher likelihood of winning or placing in the Grand National, with relatively better profitability.

1. The highest winning percentage (Win%) is found when horses have 10 runs in the last 365 days, with a 15% win rate. This is followed by horses with 8 runs, with a 7% win rate.
2. The highest place percentage (Place%) is found when horses have 4 runs in the last 365 days, with a 14% place rate. This is followed by horses with 7 runs, with a 13% place rate.
3. In terms of Profit/Loss (P/L), the most profitable number of runs in the last 365 days is 8 runs, with a P/L of 110. This is followed by 9 runs, with a P/L of 42.
4. Horses with 0 to 3 runs in the last 365 days have a win rate of 0%. The win rate increases to between 1% and 7% for horses with 4 to 9 runs.

Based on these trends, we can conclude that horses with 8 to 10 runs in the last 365 days have a higher likelihood of winning or placing in the Grand National, with relatively better profitability.

1. Horses with no previous wins have a 0% win rate and a 6% place rate.
2. The highest winning percentage (Win%) is found when horses have a maximum distance win of 4m2½f, with a 33% win rate. This is followed by horses with a maximum distance win of 4m2f, with a 13% win rate.
3. The highest place percentage (Place%) is found when horses have a maximum distance win of 3m2½f, with a 23% place rate. This is followed by horses with a maximum distance win of 4m4f, with a 22% place rate.
