I guess that I am a bit late to the party over here since I have been using another tool for some number of years but have recently been given some reasons to investigate over here.

The link above is quite interesting however I do not see the "U" category of upgrade buckets such as RU and OU nor the "P" category of RP and OP. Are they to be found on KVS? They are actually more important to me than the award availabilities (which can usually be overpowered by throwing more SkyPesos at them until they give you what you need).
