Short First Year Safe Harbor, pro-rate compensation limit?

We are calculating true-ups from 11/1 - 2/28 (pye), using just the compensation for this period. Two of the owners will be over $245k during this period. Is it ok to use their actual comp, limited to $245 for the 11/1 - 2/28 period, or should the $245,000 be pro-rated?

Is a short PY? If yes prorate.

Is is a full 12 month PY but 401(k) becomes effecive 11/1, then don't prorate.
