MATCH() function can't locate hours - indexing

Question

I've created a Time Sheet for my dog walkers to fill in. They enter TIME STARTED and TIME ENDED for each of their dog walks and then a TOTAL TIME is generated using the =X-Y formula. This TOTAL TIME is formatted to be displayed in hh:mm but its true VALUE is a long integer.
Using the MATCH and INDEX functions, I've set up a formula to match the TOTAL TIME value generated to an index on the "Payment Schedule" sheet and locate the respective payment.
I keep getting errors that state the total time VALUES can't be matched but I know that formatting isn't the issue and the values are clearly on the "Payment Schedule" sheet. And when the MATCH function does return a row it returns the incorrect row, which locates the incorrect payment/rate.
Here is the Google Sheets I'm having trouble with.

Answer 1

Found the answer on another website:
it's floating point rounding error on the time values. I don't fully
understand what's happening, but I was able to reproduce it on my
system, and I found a work-around: Change your formula to
=INDEX(B:B, MATCH($I$4+TIME(0,0,1), A:A)) This adds one second (TIME(0,0,1); the arguments are TIME(hours,minutes,seconds)) to the I4
value; that seems to be enough to get it "over the hump", so that it
tests as being ≥ the value in A4 (or A7 or A10). BTW, I tried
TIME(0,0,0.9), but apparently TIME() won't honor fractional seconds,
and so it just treats that as TIME(0,0,0); i.e., just plain zero. If
you want to get a millisecond, you can use TIME(0,0,1)*0.001.
