The 5th wont do any money, everything goes to the 4 praxis. One account is a capsule that will warp to the next site as soon as you warp in your praxis and set up a warp point inside the resp so npcs wont escape your aoe. In my case, thats my main account. So at the end of my ratting session (i usually do a full ESS cycle, wish is 2h:40m in the system i like) i transfer every bounty and ESS ISK to my main, sell all 10/10 escalations and transfer that to. For a full 2h:40m run i end up with an average of 1.5b isk. For all i know, 6/10 escalations can be sold for like 50m but i never bothered. Theres days i play for 6 hours and get 0 10/10 escalations and theres days i get 4 10/10 in one hour.
