This is not something I want to do if it doesn't help.. The ultimate gain is to get the minimum bids to come down just a bit.
I've managed to get thousands of 0.03 and 0.04 great bids in other campaigns but the campaigns pre-date the Quality Score implimentations of 2006/2007.. This campaign is new..
After that, work out what's converting, what isn't (or other analysis depending on what your goals are), & adjust the bids from there by each keyword.
In *theory* the higher positions & CTR that you paid for early on should help to improve your history in the short term & help with overall CPC reduction. It also depends on how long you can run at a high CPC though, depending on your budget, business goals etc
I think there is a connection between paying more money and getting better results...If thats what you're asking...
