ACE question regarding Chinese Team Bonus

Got a question about Chinese’s 10% food team bonus, is it even correct in the genie editor? So without a chinese ally, a farm has 175 food, which the three upgrades add 75 food / 125 food / 175 food respectively. So for the Chinese TB, there are four effects. They all use Resource Modifier to add an amount to 36 - Farm Food Resource as a number or something, which I understand.

  • 402 - Chinese Team Bonus: this uses a value of 17.5 or (base farm food x 1.1), which is added to the farm without any upgrades to give ~193 food. This looks like 10% to me. Yep, but what about these?

  • 831 - Horse Collar + Chinese TB: uses a value of 9.375 or (75 x 0.125), which increases the additional 75 food from HC to ~84 food.

  • 832 - Heavy Plow + Chinese TB uses a value of 15.625 or (125 x 0.125), which increases the additional 125 food from HP to ~141 food

  • 833 - Crop Rotation + Chinese TB uses a value of 21.875 or (175 x 0.125), which increases the additional 175 food from CP to ~197 food

Effect 402 is 10% more food, but the other three… are these 10% or are they more… like 12% to 13%. Shouldn’t the values of the above three be 7.5 / 12.5 / 17.5 because 10% is 0.1, or is 0.125 actually correct here?
