My 430 shave Feather had not been recovering as well recently, so last time I did 300 turns (150 full revolutions of the blade) on my Allegro. 100 each on the Black, Green, and Leather hones, and then my usual on the Twinplex, which is now between 160-220 cranks: 30-40 immediately after shaving, 100+ later, 30-40 immediately before shaving. The improvement in the blade is very noticeable. (I will repeat the Allegro every 4-6 shaves.)After the shave I turned to the Allegro and Twinplex again, this time using a @LJBraaten algoritm - 40 turns (which is 20 full revolutions) on each side of the Allegro and 40 turns on the Twinplex.
The Allegro is the most time consuming. The Twinplex doesn’t take that much effort. For the 100+ cranks I’m usually doing something else, like sitting around in the bathroom

A newer blade probably doesn’t need that much attention. I note that both devices recommend very few revolutions. But for my blade, that ship has sailed!
