that came from this thread :
Fill up ESI data... a study that i think must be sticky in the skill section.
The use of this study is simple, es i want sell all my 5000 longblade skills points, to do this i need a 188 ped ESI or some between 114 and 118 ESI.
But what about if i want sell just 500 of my skills point? how much TT esi i need ? I was considering, for this example that if i need 114 esi for 4627 skills points and 188 esi for 5319, to sell 629 skills points (5319-4627) i need a 74 ped esi (188-114).... it s right?
Other example, i have 1067 skills point , to sell them i need a 3,90 ped esi. To sell 50 skills point only i need a 0.56 (3,90-3,44) ped esi, right?
all this is justifiable from the fact that the skills point are not linear but exponential, so the skills between 2000-2100 are really different to 0-100, so in the first case i need a bigger esi.
thx for help
