Ask PG: On-time YC application form replaced by late one?

Will the application form I submitted before the deadline be overwritten if I submit a late "updated" application as well?

I want to make certain YC has the opportunity to hear my vastly improved (and shortened) product pitch as well mention material progress I've made.

But...I don't want to lose out on a full review by ending up in the "late" pile.

Suggestions?
