My char has 440 total skill points and 109.0 Peace (110.0 with jewels). My last 0.1 GGS was 7:45 last night (I am a compulsive record-keeper). It's now 9:05 pm, roughly 25.75 hours since last GGS. Stratic's GGS table indicates that at my Peace and total skill levels I should get a GGS gain every 20.7 hours (at 109.0 real skill and 500 total skill mark) or every 24 hours (110.0 actual skill and 500 total skill mark). I've just successfully Peaced 50 Cus and achieved 0.0 skill gain. Breaking news! As I am writing this, the 61st Peacing attempt (a failure) produce 0.1 Peace gain. So, for me, GGS means somewhere between 1 and 61 successes/failures you are GUARANTEED to gain 0.1 skill. It's good to know the system really works!
