Please hang on with me here .................................
Gunnislake Railway Station has a flat and level carpark, and with a gentle slope into it.

It's near the top of the hill, and I sometimes turn in and check out the rolling distance of my bikes (or bikes).
I stop exactly at the lamp post on the left, and start without pushing off, then clip in making sure I only pedal backwards to do it.
I freewheel along until I stop.
Measuring the distance of the slope and the level section using the Mick F Standard Pace, I find that the slope is 15 MFSPs long.
The level section to the Base Reference Position is 80 MFSPs.
Mercian stops at BRP plus three kerbstones. This is repeatable and is only variable by a couple of feet no matter how many times I do it.
If I do this with Moulton, I find that if reaches BRP minus three kerbstones.
Now, here's my question:
When I roll with Moulton, it feels as though it's rolling just as well as Mercian.
By assessing the speed as Mercian enters the flat bit, it's much faster than Moulton.
The mere fact that Moulton doesn't roll as far as Mercian, is down to the start speed, and not the rolling resistance.
How can I prove this?
Could a 406 wheel bike not accellerate as fast as a 700c wheel bike?
If so, how can I measure the accelleration differences?
Should I start higher up with Moulton to equalise the speed?
If so, how do I measure it?
