400 hours is more than I got a couple years after you, but we had a requirement in Tones to log 75 hours of other time. In practice you'd do out and backs with a partner and IP. Each stud would like 2.0 primary and 2.0 other. Consequently we finished UPT with closer to 300 hours than the 200 the 38 guys got. But the extra was all worthless other time. 94-05 must have been one of the first Tone classes, probably still working stuff out if you hit that much time.
