Let's offroad / mountain bike / mtb / ride dirt

Off the top of anyone's head, do you know if a Cane Creek Db coil IL 200x50 is identical to a 200x57, save for a stroke reducing clip under the bottom out bumper? The CC website seems to suggest thats the case, but my 200x50 doesn't have a clip under the bumper, and it's definitely not 57mm stroke when bottomed out. Unless they're including the bottom out bumper, fully compressed?

I've emailed Cane Creek but no reply

Cane Creek finally replied, and they've confirmed what I thought. My shock was built as 200x57 according to the serial number, it just needs a clip under the bumper to make it 50mm.
The upshot of this is that I've been riding with 17mm more rear travel than I thought I had, which has made me not only reconsider if I do actually need a longer travel frame, but also re-evaluate whether I know how to use a ruler properly 🤷🏼‍♂️
