It's mostly used by people flying SAR missions. You keep increasing the

Ah, OK. I had read about trans-Atlantic flights using an offset and assumed
it was available in these WAAS boxes given their extreme accuracy and the
increased chances of mid-airs on climb-outs and descents.

It would be nice to use it on Victor airways, had they only offered
offests in 1/10 mile increments.
