I would expect the amount of cartridge output due to this, one of many, bit of spurious vibration, will depend on the record support. Something with vacuum hold down or a properly engineered clamp system will have the least, something with a felt mat perhaps the most (perhaps why so many people like Linns and Roksans ???)
But why bother about quantifying it?
AFAIK there hasn't been any published engineering analysis of the distributed mass dynamic response of a record player system since computer power and software cost made such a thing plausible. I don't see any likelihood of one being done by any company currently in the business, which proceeds with marketing phrases not far removed from witchcraft and technically erroneous statements based on applying static thinking to a dynamic system. If one has been done it has not been published. A well known cartridge manufacturer did approach a friend of mine to do an analysis of the dynamics and magnetic linearity of their cartridges. The first look showed significant areas of error so they decided not to go ahead with the engineering work... Neat and inexpensive solution.
I don't concern myself with the relative magnitude of spurious vibration pickups inevitable in my record players. Experiments when I did work in the business showed that eliminating all of them was not possible anyway.
I rejoice in the ability to tune the sound of record players to taste, if that is what one likes, which isn't feasible with CD. If one doesn't want the faff LPs are no longer the only low cost music carriers they were when I started buying recorded music in the mid 1960s so there is another choice.
Mostly I listen to CDs but still enjoy my old LPs whenever I feel like listening to them. I probably won't ever buy a new one again unless part of a set with compelling artwork like a Laura Marling set I bought.
I think this gets to the essence of the issue with vinyl. Why bother with the science and engineering. When LPs were all there was for home music playback, it made sense for manufacturers to keep improving the engineering to get better and better results. Lower wow and flutter, lower rumble, lower speed drift, better isolation and so on. Ditto with cartridges, better tracking, lower distortion etc. CD changed all that. If one wants technically good results at home, there has been a system that does that for now 35 years, and playing LPs is now done for reasons of nostalgia, because that's what the music one wants to play happens to be on, or just because one prefers the sound of distortion, noise and wow&flutter.
Turntable and cartridge manufacturers now sell the sizzle, not the steak, as the steak is as tough as old boots.
I love my two turntables as examples of superlative engineering and enjoy an evening of playing LPs, and even occasionally 78s, but any quality I get out of it is more of a surprise than expected as if I want quality, I have CDs for that.
