So I finally got the big test done, conducted as follows- 16AWG re-wired Stryfe, with voltmeter, stock motors.
30 new darts per power source
Constant firing rate of 110 darts/minute as that was as fast as they would shoot reliably over the chrono.
New batteries and packs- only mid level cheaper packs and cells were used to reflect "average Nerfer" buying pattern. Most commonly used and recommended brands selected.
Ultrafires and  pack peak charged before the test- IMR's were charged 3 days previously.

The spreadsheet of the results is here.

Another point of note was that I had to buy two pairs of TF cells in order to get a consistent pair, two failed, one was a complete dud, the other peaked, then almost completely discharged upon testing. These were not the cheapest ones available, in all the time I have used them I only ever had one dud IMR in about 24 cells.

This is a Britnerf exclusive at the moment, I will add the voltages as I record them off the video later.

Very cool... At the risk of demanding the moon on a stick, did you consider adding a stock test (ie stock blaster and standard AAs) or maybe a rewired-with-AAs? It'd be really interesting to get a starting point of 6V.

The stock test is in the stock blaster data thread, look there. I will do the baseline data with new Alkalines on the re-wire tomorrow.

For those interested I have added the battery voltages to the spreadsheet. For lazy people-

Trustfire                       IMR Efests                    Zippy Compact 2s Lipo
Start Voltage- 8.1v   Start Voltage-8.3v      Start Voltage- 8.3v
No Load- 7.7v           No Load-7.9v              No Load- 8.2v
Load- 7.4v                   Load- 7.5v              Load- 8.1v
End Voltage-7.9v   End Voltage-8.2v      End Voltage- 8.2v

We should do some audio analysis of spin up time to prove the difference that current supply makes. Easy way to quantify responsivity (that a word?).

The other thing to look at is the total consistency across the board, even with crap cells there was no "flywheel drop" on the range of figures. I got a slightly higher first shot as expected but beyond that it kept shooting pretty much the same. On the 2s pack it's in the 5kg springer zone on total performance, which was a bit of a surprise.
