AmLaw 200 came out the month after AmLaw 100 last year, but last year's AmLaw 100 didn't come out until July. If the AmLaw 200 does take longer it's probably because there's more firms in that range who are reluctant to disclose this info.

It explains Wachtell, since (I think) they charge a flat fee (% of MEGADEAL value) instead of hourly billing, and when they're productive that translates into a lot of deals/money per hour.
Otherwise I think the difference might be in billing, but perhaps in terms of which practice areas make up their revenue. Litigation requires more hours and bankruptcy bills have to be disclosed to the court, and there's probably more subtle differences among the Wall Street firms also.
