Cavalry Vs. Infantry

Im wondering How many Cavalry i would need to Kill the amounts of Infantry as shown using Cavalry vs.Infantry.If no losses is not possible hw many to possible drastically lower the loss amount.

35,000 =?
58,000 =?
80,000 =?
139,000=?
180,000 =?

Ive been experimenting using Max Stats /Techs and idk wat the right amount .Using 11k Cavalry vs.20 k Infantry i still sufferes 128 Loses.

I want the losses at ,at least 30 or less if no losses is not possible.

I Know the ratio is about 1.9 thats with max equipment and enhancements so you might need few more if equipment enhancement quite low.
so for 35k Inft You Need 25K Cav Losses are about 20-30

That would be hard to do but i think it needs some testing

1.6inf:Cav at base stat

42858
71021
97960
170205(for 139k, for 130k 159184)
220409
