I seen it mentioned several times that a 250 + a geerlok will give a skill of 263 or so...
Not true. Remember! The net adjuster level of ANY skill regardless of bonuses cannot go above 252.
IN actuality, if you have a geerlok, you are a grandmaster at 240 (+12 for geerlok making 252)...
That helps a lot because the last 10 points of a skill can be horribly drawn out and difficult / expensive, to get!
