I did measurements for 100 unique items once. It was gruesome. A lot of garments are difficult to measure, so you are sure to displease someone. Compounded on top of that, the measurements typically given are about 1/2 of the measurements needed to really show the fit. I have been seeing a lot of retailers move to the "the model is 6', 40" chest, 32" waist, and wears a M", which is undisputedly easier, and arguably a better system, as long as the fit model is a true fit model, and not a wannable runway model. 6'-6'1", size 38-40, with no more than a 8" drop, and no real bulkiness, but not super skinny either. Frankly, if you are not within a pretty "average" body type, it's unlikely that you are going to get a good idea of fit without trying on the garment, in any case.
Don't get me wrong, I'm sure it's a relatively time consuming process and as you note the measurements may not be made the same way the consumer would. Still I find it helpful with some brands that I'm not familiar with and in my case it's not like I'm in a market where I can just go try on a lot of brands that interest me. Of course none of that is End's problem and they have a business to run on top of them surely being willing to provide measurements upon request. However for me it's unfortunate as they have since I've been buying from them always provided them and they've been quite helpful, and this is coming from someone who has spent a small fortune with them over the past few years considering all the Cabourn alone that I've purchased.
