ND this fact is simple:
if ronnie was noticably drier in 98 as opposed to 99 as Peter says,
there should be AMPLE pic evidence of this.
but there isn't.
Hint: if you have to scrutinize a video to search for a tiny difference when you can't see a difference in any of the pics, it usually means there isn't really a difference at all...
if you need a microscope to see a difference, the difference is insignificant.
