For me, once I know it's perfect off the Nani 12k, which usually isn't more than 30-40 laps, a quick inspection under the loupe, then 50 laps on SRD Roo strop, then 50 again on Kanayama.
It's re-tape the razor, generate a nice slurry, and on a 6 x 2.5 stone, I'd say 25-30 minutes, don't count laps, just slowly watch the slurry, hitting the stone with the razor at different angles, starting off heel leading, watch the slurry, X-strokes, watch the slurry, straight back and forth, some sweeping strokes, rinse the razor couple of times, and slowly dilute until clear water.
Then back for another 50 laps on each strop, I like to have a shave just off the stone, but usually then follow up with about 10 laps on a Japanese linen strop board I made with a couple of X marks of CROX....
Here's the board I made, works beautifully and was an uber fun project:
