Here you go…I do a bulk ferment first, so my timing is different.

i have also made the “one hour” sourdough discard dinner rolls which are delicious, you’ll find the recipe in the discard grouping if you are interested.
i also did a bulk rise first with one s and f at 10 minutes or so . This was half the recipe, the rolls are quite large. I’ve also made it with 8 rather than 6 rolls. I did not brush with egg prior to baking but did brush with softened butter when they were removed from oven.
ETA…my discard is half white, half rye and it is not old.
