A 45-degree offset travel piece was cut to the flat distance and falls short
A 45° offset travel piece follows the diagonal path, not the flat throw. Use the 45° multiplier, then subtract the fitting takeoffs before cutting the spool.
Do not cut the travel spool to the flat offset distance and expect a 45° offset to land correctly.
Check
Measure the actual offset throw, not the guessed gap.
Use the 45° multiplier for the diagonal travel path.
Subtract approved fitting takeoffs or center-to-face dimensions.
Confirm the duct still lands on the next centerline before cutting.
Dry-fit or mark the spool before sealing the run.

Say this to your foreman
I measured the offset at [measurement], but the first spool was cut to the flat throw and landed short. I recalculated the 45° travel path and fitting takeoffs. Do you want me to recut the travel piece to that layout?
