Combines with a trivial of more than 100 points over your current skill will not count toward trophy evolution. For the purposes of evolving the tradeskill trophies, all combines with a trivial of higher then 350 are considered as 350. Once a trophy has reached level 6/7 (six of seven), you must have at least 300 (unmodified) skill to increase it any more.
The experience gained on a success is equal to the trivial of the combine up to 350. All 350+ combines give only 350 experience. Therefore, your trophy would evolve faster making 350 trivial combines than 301 but even at 301, it would eventually get there.
