Training research at the trainer

[rahmani]

As a dedicated quadder, I seem to be choosing mobs to kill that do not drop any runes. Therefore, I have chosen to just increase my skill level in research at the Wizard trainer.

Since research is a trade skill, the formula is 5(Level - 15) for the skill max, which means at level 49, I'll have 170.

How safe would it be to attempt to combine Rune of Frost and Rune of the Astral at 170 for Ice Comet, when the trivial is 184, I realize I will be quite below the trivial, what are the chances of me failing?

(It will be 14 points below trivial.)

I would hate to wait until 52.
