I was about to reply when Volatpluvia beat me to it.
First, let me add my complements to Raszpla. The lock is magnificant. The patience and care needed to produce such a fine lock is hard to imagine. This quality places you in the elite of gun makers.
Regarding the wheellocks ignition speed, my comments here are based on a single wheellock - the one made by Volatpluvia and videoed at Friendship in 2005.
The ignition speeds of both flintlocks and wheellocks place us in a range where human senses are almost useless except for general impressions. I have watched thousands of trials and say with certainty that human senses are at best unreliable for these short duration times.
The difficulty with wheellocks is that there doesn't seem to be any visual warning that ignition is taking place. On Volatpluvia's lock the wheel is exposed. We made a dot on the wheel with a felt marker so we could see when the wheel began to move, when it came to rest, and if there was any back lash. At 5000 frames/second we could see all of this, including the backlash all happening well before the pan ignited. (backlash was maybe 120 degrees IIRC)
In trying to say with certainty which is faster, wheellocks of flintlocks, I would maintain that we don't have evidence to support any reliable conclusion. Volatpluvia's wheellock speeds falls within the range of the 80 + flintlocks I have collected. It is slower than an original Manton and faster than "slower" flintlocks for which I have times. Whether or not Volatpluvia's lock is representative of wheellocks is unknown, but it is the only one I have to go by. It would be fun to have Raszpla's marvelous lock in front of a 5000 fps camera and see what it can do.
My "unsupported"
gut reaction is that both types of locks overlap eachother based on the quality of flint edges and pyrite condition. If we had data on more wheellocks and more trials with each, we could make a better educated guess. It's quite possible that Volatpluvia's lock may have been 15% faster or slower on the next trial, based on pyrite condition. That happens on flintlocks regularly.
Finally, with 80+ flintlocks, I can say pretty well what flintlocks can be expected to do. With one wheellock examined, I'd say the jury is still out. But, I will remain skeptical of conclusions based on eyes and ears. The term "seems faster" used by Volatpluvia and Taylor is a good choice until we have more than senses to go by.
