On my trip over the week for the Half Marathon, I asked my old CM friends from my area what/if anything has changed. Based on their response, it doesn't seem like the merge ratios themselves have changed at all, and they're still using the phase cards I have in my wallet. That doesn't mean they're working by those merges, as if only 1/3rd of the original system is used, then you're rarely going to actually need to use the ratios.
Regarding standby, the lines DID MOVE QUICKER. The posted waits were also outright lies more often then not (suspiciously high for FOP). I watched a family of 8 pay for LL for FOP and I decided I would time the 60 minute posted wait. My actual wait? 7 minutes. Something was off, and I feel bad for that family.
