Also, if you're on an assumed temperature thrust reduction, the aircraft will be performing better than calculated because of the higher air density at the actual OAT, so you already have a margin over the worst-case V1 failure.
If you're trying to look good in the sim, as the OP implies, then you might as well follow SOPs as the sim is the one place where the aircraft performance will be as the "book". Why make life more difficult?
