This is funny. You only need 80.1 not 81.0 to rez. Actually might beable to rez at 80.0. I dunno. Because unlike most people in this game. I only run all chars with real skill. Having anything under gm in a skill is just a waste and a sign of laziness.
To be frank, I'd never tried leaving it at 80.1, but I know 81 works for sure!
Hey, I take offense at you calling my 81.0 point in anatomy as unreal skill! It is real I tell ya!
And it takes as much effort to raise it to exactly 81.0 too (includes time to lock all other skills, then go buy another skill to reduce anat from 100 to 81).
Regarding having skills at lower than GM, yes, I hate it too. Would love to have all my skills at GM, but sometimes you don't need the higher abilities that higher skills gives you. Also, depending on what you use it for, there are some skills that at useful at low levels, but only marginally more useful at higher levels.
eg 1 - Chiv, in pvp, you don't need it at a level to cast EoO. In PvM, if you use healing to rez, you don't need it at a level to cast Noble Sacrifice
eg 2 - Tracking, it's very usable at lower levels to track GM hiders. The advantages of higher or GM tracking doesn't justify the skill costs
eg 3 - Ninjitsu, for thieves, you'll only need 50 to use smokebombs and 70 to use ostard form
The skill points saved can be used to add another skill to the template

This is a part of the game that I love too!
(I also loved tweaking my cars in carwars and mechs in battletech to optimize the hell out of them heh)
