I've heard that method mooted before.
I'd end up squeezing 47 reps in between 9.30pm and 11pm every night which would defeat the object somewhat.
On a side note to this there was a documentary over here about 15+ year ago on some kids joining the Royal Marines. I think part of the entry test for Officer candidates is 12 straight pull ups.
This one lad had worked very, very hard on his ...... chin ups.
So he can do 12 chin ups consecutively, perfectly, off a bar but he can't do 12 pull ups consecutively off a beam which was the requirement of the test.
He failed and was told that in future he should read instructions.
Harsh but totally fair.
I'm pretty good at chins, pretty poor at pull ups
