I haven’t had adjustable chainstay length since my TR250 years ago but I could tell a difference and I want to say it was only 5mm. Longer for more straight line stability and shorter for more ease in cornering. After riding an XL Sentinel for a long time, I tried a L Spire which has a slightly shorter reach, chainstay, and wheelbase than the XL Sentinel and I actually felt a bit unbalanced, like I was hanging off the back of the bike a bit more than on the Sentinel. I could corner a touch easier but missed the feeling of being more centered (probably mostly due to the fact that I should be on an XL at my height).
