If you finished P-1 on 2/16 and lost the exponent on 2/17, you may not be far enough along with the double-check to make this effort worthwhile to you.

I can't answer about why you lost the exponent. However, I can tell you that curtisc did not do a PRP with proof. Thus, the exponent does need a double-check.
