Rodinal one Shot / Kodak trix 400 pulled @ 100

Hello all,
My last roll of film (kodak trix 400) was accidently taken overexposed 2 f stops. That's why i need to develop it at 100asa, instead of 400 with Rodinal one Shot developer. My question is, for how long should i keep continuous inversions in the beggining and then how many times should I inverse the tank during the 7 minutes of developing?
Thanks in advance for any of the answers/suggestions

Rodinal takes off about a stop of speed by itself, so you effectively only overexposed by one stop, which is not so bad. I would do 7 minutes, agitation 30 seconds initial and then one or two inversions at the start of each minute.

Film is quite tolerant towards overexposure, less so to overdevelopment. Tri-x is one of the more tolerant films in all respects, so don't worry too much about it.

In would follow the normal agitition with the rodinal/ro9 1 shot, that is continus forn the first minute then 3 inversions every 30 seconds

I would agree with either of the two posts!
