The only problem is that the repet tables are based on the rapid
offgassing of helium with a relatively low nitrogen uptake.  

Thus, by making the successive dives on mixes with more and more
nitrogen, there might be a problem with more residual nitrogen on
board than the repet tables allowed for.

Repets with mixed gas are a very grey area, and very little research
has been done (I do not know of any doppler studies on trimix repets
other some that I did on a single repet with the Submariner tables.  The
Submariner repet tables were custom generated for the specific dives,
and the bubble scores did increase on the repets, but were not greater
than a K-M 2 on the single repet.  Sample size was only 6 divers, so
the validity of these observations are open to debate.)
