Ok I am going for 55 slayer and got a 67 troll task. I decided to kill troll generals. I put that in my the planner and i was 6k xp off 55 slayer. So now i have 37 to go and i put it agian in the planner and im suppost to be over 55 slayer.

 

 

 

Anything wrong with the planner?

Moved to Calculator forum

Can't find anything wrong with it.

 

 

 

With a starting XP value of 180000, I tried inputting 67 Troll Generals, final xp was 190083. Manually adding 30*150.5 to 180000 (netting 184515) and then inputting 37 remaining generals also gets a final xp of 190083.

 

 

 

So I'm either misunderstanding you, or you made a small error somewhere.
