Survivor numbers and team deployment are very different things. We stumble through this problem all the time in MR, though intelligent SAR Commanders who use the stats to try to see into the future mitigate some of it through their fuel policy. Take an S-92A for instance, the big bruiser type that is about to retire from Scotland and Ireland. Yes, wouldn't it be great to have all that space for deploying people to do big searches? Contracted number of survivors = 8. Advertised maximum = 21. MRT carried upon first arrival at summer incident after 48nm transit = 3!
