Total impulse can be calculated from the area below each curve. If you can integrate such curves you can measure if there's a significant difference between them or not. With BrO you get something more like a kick, while withour BrO you get a longer (and probably safer) burn, less speed, but not necessarily less height. Try using less BrO and you may get an intermediate curve. 2015-03-08 21:05 GMT-03:00 steve ghioto <ssmgg@xxxxxxxxxxx>: > Hi guys, > > On the archive list from last June I noticed a few posts concerning BrIO > as a burn rate enhancer and if any follow up work had been done on the > issue.
