After 14 days straight, that is a ton of reps. Doing this results in close to 2,800 intense reps.
Most in the same time frame would hit around 700 reps. If you did the classic 10 reps at 5 sets for 14 days. But we know most just work calves 1-2 times per week so you could lower that number to around maybe 350-500 in the same time frame.
You are really breaking down the muscle with no recovery for 14 days. It needs a good deal of time to regrow. You could probably get away with 7 days recovery if one wanted to, but I would rest them for 14 and then hit them again after that test period.
