His advice was he GM'd the skill using Dungeon chests only. I plan to follow his advice with occasional breaks to try for gains on Treasure map chests, and Prison camp chests. I will simply document this journey with regular updates.
I made it up to 80 skill with a single chest, cast magic trap on it and remove trap on it. Using a macro for 3 days got me the max gains to 80 skill.
I started my quest 2 weeks ago at 80.4 Remove Trap skill.
July 15th, my skill is 81.8 using dungeon chests casually to date.
July 16th 4 hours game play - at 83.2 now - averaging about 0.3 an hour - one chest got me 0.2 gains before untrapping

July 17th 4 hours game play - at 84.2 now
July 17th 1 hour game play on Prisoner Camps - NO GAINS at 84.2 skill.

July 19th 5 hours of dungeon chest RT at 86.7 now - gained 0.6 on one chest before it untrapped, another 0.4 and 2 - 0.2
July 28th after a few days off, 3 more hours of game play got me to 88.0 skill

Oct 2 2 hours of play - 0.5 gain total ... at 88.5 now
