The Zippy's now seem to be effectively 15c packs, not liking sustained current draw much over 30A.
Interesting data, but don't forget how those lipos are being marketed;
From Hobbyking site;
TURNIGY® Batteries explained
Zippy: Great value for money. Average Cycle Life* (100+) and minimal voltage sag under load.
TURNIGY Standard: Excellent value, Longer Cycle life* (160+) and very low voltage sag under load.
TUNIGY nano-tech: Unbeatable performance, Longest Cycle Life* (250+) and almost 0 voltage sag under load.
*Cycle Life results from discharging at full C rate to 3v. End of life when battery has 80% capacity.
Not sure how the Rhinos fit in, but I'd say those are probably considerably higher end lipos compared with the Zippys.

Keep in mind that you can in fact delete those entries as they are just registry entries. I think there's probably still a limit on how much USB devices can be registered in Windows simultaneously and some indeed seem to re-register basically every time you connect them physically if it's not the same physical USB port each time. At least this seems to have been the case with Windows XP and Vista.
