Dave,
I recently shot a roll of SilverTone 400 at EI 200, but accidentaly developed it in Rodinal 1+100 for 37 min which is time to get full speed, i.e. 400 ISO. My negatives are awfully dark. Bear in mind, Silvertone 400 is a real 400 ISO emulsion, so you will have to pull it (underdevelop) when rating at 200. Don't repeat my mistake 🙂
Eduard.
