Oops. I was just putting my v4/LPS together, and I realised that the comparison I made between the stock v4 and modified v2 wasn't a fair one. Everything else hadn't been equal after all.

The v2 had an OA02 analogue card, while the v4 had an OA03 card. This obviously tipped things in the v4's favour. Please accept my apologies for the misleading result of the shoot-out.
