I'm thinking there was a script a few years ago that "intelligently" added the plays for you. Spanning them out between the "Last Sync" date and the "Last Play" from the iPod. I can't recall what it was called or what version it may have been for, I may be thinking of an old 2.x script. I may have a look around in a minute to see if I can find it... or come to the realization that I made it up in my head, Lol.
EDIT: Actually, it looks like Bex has already included functionality like this to his script. I didn't think he had it set up to add the plays between x date (such as last sync) and x date (such as today). I honestly don't ever use the "Add Plays" portion of his script, instead I only use it to remove the "iPod plays" (personal preference). Though I think this is what I was vaguely recalling. It's old though, so Bex's is probably your best bet if you decide to have a go at adding the plays.
