anyone has guide for using cav to attack lvl 1 to 5 fortifie

anyone know how many cav do i need to minimize the loss when attacking fortifield level 1, 2 and 3, maybe 4?? anyone has guide for this?

currently i am using approx over 1k cats to attack farm fortified, but i want to change it to cav for speed farming.

if ur giving me ur stats i could calculate it...

attack 20
speed 87+6(lvl3 horse)
defense 20
fortune 20+8(ring)
current lvl: 3rd Earl (in server 13 :"D)
After max out speed, i go for defense (ppl recommend)
currently has 3k inf, 1k cav, and 1.5k cats
i wanna switch to cav farming and start to build up cav armies

shall i generate it with max speed or ur current stats

Tech:
marching skill lvl 7
attack skill lvl 5
defense skill lvl 2

current stats or with 145 speed?

This is my current stats

no.. if i should genarate it with ur current stats

also, when i use cav attack, who do i attack first in fortified. i don't have experience using PURE cav armies
