My daughter mistakenly grabbed a roll of APX25 (35MM) I had and shot the roll thinking it was APX400. I plan on developing it in Rodinal (my usual developer). Any ballpark suggestions for pushing it this far?

The worst case a friend experienced was Efke 50 at 400. I worked out something like 15 mins in Acufine, he finally used Ilfosol for 30 min. But Efke 50 in ID-11 is almost 100 ISO. With Rodinal another friend pushed HP5+ to 1600 in 80 mins 1:100, agaition every 5 mins. I do not have any APX 25 in stock to test it, but I would advice a clip test in Rodinal 1:100 for 90 mins with low agaition.

Forget the Rodinal and get a speed increasing developer like Acufine, DDX or Microphen. Expose another roll and do some clip tests. Develop at 80 deg. F unless you want to grow a beard while doing all of this. Expect no shadow detail.
