Joes said: On your trip, did you actually see your Fuel Gauge go up any bars (in addition to your RR increasing)?
Yes it did once. Here is a part of my log...
16 bar , rr: 139km, at the start.
15 bars, rr:130 at 8,6 km hilly.
14 bars, rr:118, at 12 km, steep up road for 5 km.
15 bars, rr:125, at 15.5 km, downhill for 5 km.
14 bars, rr:117, at 20.4 km, hilly. And then 13b at 25.5 and 12b at 35 lightly down.
On that mountain trip, the worst efficiency I have seen was 3km to the bar on steep uphill and the best was 23 km/b, on long 15km light downhill, but without gaining a bar.
The trip was 106 km, from St-Jean (SJ) to St-Magloire (SM) at 1500 feet altitude, but having to go up 6000 feet and down 4500 to go and the reverse on the way back. I have a formula to calculate the total distance I could have done on a charge ( from 16 bars to 0 before the reserve), going the same speed and same conditions. I call it DTa and DTb. Distance Theorical according to RR or to bars. So ...
DTa : SJ to SM was 132 km and SM to SJ : 161 km.
DTb : SJ to SM was 129 km and SM to SJ : 153 km.
Another way to calculate the efficiency is the average number of km for one bar. So
SJ to SM (more up): 7.8 km / bar. Going slow first 30km on the flat to preserve energy.
SM to SJ (more down): 9.6 km / bar. Help from back wind last 30 km. Oh I forgot, also 20 kmh faster with back wind, and all the way down SM to SJ at 10 kmh faster.
