The fastest checkmate with quintupled pawns present

What is the fastest checkmate with quintupled pawns present?

This is what I've found:

Do you find any faster way?

Oh. I've found a fast checkmate with sextupled pawns present:

Even faster!

If you think there are lot of wasted moves, why don't you try to find a faster way?

This is quite fun!

Beat that

nice, only 13

Why am I looking at that thread ?

Technically a pawn can't REALLY reach the final rank, because it transforms upon entering it, but for that moment of decision what to transform to, you could argue, that SEPTUPLED pawns are possible...

Also for that 'SEPTUPLED' position, you need to capture a total of 12 pieces to shift specifically only either into your e- or d-file, leaving only the enemy a- and h-pawn, either the enemy b- or g-pawn and the enemy king behind. All other enemy pieces must be captured in the process... So what's the fastest game to achieve this (and possibly checkmate the enemy upon transformation)?

edit: Sorry, I made a mistake here. You can of course utilize the enemy edge-pawns if they shift towards the middle before, capturing your own pieces. This might or might not also be a part of (one of) the fastest way(s) to do this...

Right, quintupled and sextupled pawns are very common in actual games, but advancing one to the final rank in front of sextupled pawns, as the ultimate version of this, is unheard of. Here a basic version of it, that might be not the fastest or most beautiful one, but who cares:
