Personally I use this:
Nystul's Notebook
It accurate you just plug in your deeds and it give you the reward(s) you can even make a file and save them. I have several files saved one for each type of leather. Also I have them filed by reward though that is somewhat anal-retentive of me.
It will also import a list through UO Assist but I know you only use KR.
Yes, I know it has not been update in years but it is still accurate. and I dislike the charts over at the tower of roses.
