db - doesn't MMTC offer benchmarking services?
Here's a link that may produce some fruit.
At the least there are a lot of links to things about benchmarking.
The feature I remember most about this outfit is they organize tours (for a price) of operations for benchmarking purposes. they also publish summary reports. I don't remember the details, but they've been around a long time, if one can equate longevity with acceptance by the marketplace.
