Found it.
You're going to go to 60' on a Table 6 because pure O2 is available and in use. You're not going to use pure O2 during IWR because, like many have said, you'll tox and probably drown. Thus, a Table 6 is moot because it assumes that pure O2 is available. When pure O2 is NOT available (and, more importantly, the environment is not conducive to using pure O2), then a Table 3 is administered. What is a Table 3? It is a 21.5 hour ride from 165' on air.
So, in summary, for IWR to be effective, yes, you would have to hit a depth of 165' and plan on clearing your schedule for the next day.
Just so there's no confusion, what I'm talking about is the kind of situation where DCS is inevitable as the result of omitted deco, NOT a missed safety stop.
