I die laughing when I hear these terms applied to turntables. Plodding? Does that mean slow as in 33 1/8th or, does that mean increased amounts of wow?No. If it was such a simple thing as slowing down of the platter speed, it wouldnt have made to the market. Plodding as in transients not recovering fast enough and bleeding into notes, a time domain smear. This is quite easily heard with slow music (low tempo). It is not due to wow, it is due to energy storage in a heavy platter which doesn't have an effective drainage mechanism. A design issue. I am not a technical expert in mass and energy transfer in these devices but I have just heard enough of this nuisance, endemic to "new age" turntables.
Most of the golden era TTs do not suffer with these issues at least. They may not be quiet but they sound like music. Probably because it came from large established audio companies who hire a good team to do the job instead of the typical "1 man" companies designing TTs today.
