Total: 959s/996s/977s(flinch clay)

So: 36s slower than late to clay without candy, 74s slower with candy, 54 with flinch

Candy is 38s slower to clay, but guarunteed sandslash 2hko, has no potential to lose time on workers in the gym,
candyless can potentially lose 7-8 seconds due to cosmic power/dig.

Early:

PWT H: 27s (Dewott 6/16 without candy, 14/16 with) missing ~4s

Cheren Double: 65s/56s (candy + get 9/16 Golbat range)
Hugh Double: 58s
Skyla: 88s (candy usually saves 9s, RS range goes from 2/16 to 11/16 can't avoid Hyper otherwise)
Reversal Double: 80s (With candy, vibrava is 12/16 rather than 11/16 to die, could probably skip healing before)
Hugh 3: 79s

Post Clay:  475s Difference = 102s

Overall difference: Early is ~66s faster to Hugh3, then is way better off for the rest of the run.
