Busardo scoped it in his review. Power and voltage spike I believe he said 'round 20% if I recall while in boost mode. Though the higher your power/voltage is set the less the boost impacts it (makes sense)
we covered that here too at length about a week before Thanksgiving..... and I think Provape chimed in at one point.... I also recall somewhere someone put together a table showing the boost vs power/voltage settings and the coil resistance.
I'm referring to how the power regulation works on the P3 in general (not just boost). I suspect there's more to what the P3 is doing when power is set than just flipping ohms law on its side to display power while keeping voltage constant ... I didn't see that really discussed in PB's review (maybe I missed it) . I definitely didn't see a trace and it certainly hasn't been talked about much here,
For a long time (actually since the first VW devices started showing up) I held to the argument that the difference between VV and VW was mostly just semantics. On paper and at steady state sure it's the same and with 32-36 ga wire I'd say it's negligible....but in practice, with heavier gauge wire, as a coil is heating up, now I'm not so sure.....
Unfortunately, my P3 is out of commission and at Provape right now (along with my tugboat and batteries)- I'm sure they'll figure out what caused my problems and address it (or me) appropriately, but I can't test anything right now.
Are you setting voltage or power? Do you find the behavior different setting VW vs an equivalent setting on VV... particularly on lower gauge builds?
One thing I did test is setting the voltage on my mini to 4.8V vs setting the P3 to 14.4W (with 1.6 ohm 26ga build... that's 3 amps for the mathematically lazy)- I could sit on the mini;s button for 10 seconds before it came up to temp but the P3 took only a couple of seconds to get up to temp with boost off and was almost right away with boost on. Point being IMHO, there's more going on with the algorithm managing the output than we've discussed here and whatever it is, it's good. The only way we'll know for sure is either from Provape or by looking at oscilloscope traces of the P3 vs 2.5 with different builds.
