I do something like this.
Three sets to 100 reps.
Usually my first set is around 40, then the other two are around 30. 100 total in 3 sets.
Started out with 95lbs earlier in the year with this approach, then moved the pin a notch (20lb increments) a couple times. Today I did 155lbs for the first time - with 40, 32, 20+8 (had to do a 5-10 second break during the 3rd set, it was too much).
Today's 3-ish sets were insanely painful - after the last rep of each set, when I step off, I get a wave of pain that I only get with calf work. Almost brought tears to my eyes. Must indicate progress, right?
Calves are 16.25" cold, never measured right after a workout, but the 100 rep approach creates a wicked pump.
Some weeks I do this 3 days, some weeks only once. I do a day with higher weight, 250 or so, every now and then, and still keep each set over 20 reps, but not 40!
Is it weight or crazy volume that is best for growth?
My speed is controlled, no holding at the top though. No bobbing either.
