CUDA WU are being inacurately reported by BOINC, if a WU actually takes 20 min to crunch for some reason it shows only 1 minuite of CPU time, which is obviously grossly short of the actual time spent crunching the WU.

That is because BOINC does not count GPU time in BOINC 6.4.5, only CPU time. The CPU took 20 minutes to transfer data to and fro.

This may have been fixed in 6.6.2, if you want to test that.

Under the BOINC download page, where else? Select All versions, but be careful to read the read warning!
