Aptitudes

These letters mean different things depending on what row they’re in. An A is the baseline and gives no benefit or penalty. If you’re below A, you will be penalized, while if you’re at an S, you’ll receive a small bonus.

The first row is for the surface type, either Turf or Dirt. This rank affects your acceleration. If you have an S, you’ll receive a 5% boost. B will give -10%.

The second row is for distance. This rank affects your speed. The rates are the same as the surface type. If you have an S, you’ll receive a 5% boost. B will give -10%. If you have an E or lower, it will also reduce your acceleration by a significant amount, but you shouldn’t put an uma through that.

The third row is for style. It affects your Wit. An S is a 10% boost, while a B gives -15%. However, this does not affect your chance of triggering skills, only all the other things Wit does. Getting S in style is fairly minor but does increase your team score in Team Trials.

To be precise, here are the exact numbers for each rank.

Type	S	A	B	C	D	E	F	G
Surface	+5%	0%	-10%	-20%	-30%	-50%	-70%	-90%
Dist	+5%	0%	-10%	-20%	-40%	-60%	-80%	-90%
Style	+10%	0%	-15%	-25%	-40%	-60%	-80%	-90%

The +5% to your raw speed or acceleration converts to +10.25% Speed/Power stat (about 120 at 1200 Speed/Power). A -10% would convert to -19% Speed/Power (about -230 at 1200 Speed/Power).
