They show a nifty pic of a Mercedes 3 rotor....
The argument is that trailing is unnecessary and problematic - there's a little more to it than that. The claim that Mazda turned trailing on and off to ward off detonation is wrong - it was for heating the thermal reactor.
The reason they show the C-111 engine is to show the single plug per rotor arrangement. But note the position of the plug - it's not below the minor axis like a leading plug, but rather slightly above it. This was standard practive for single plug rotaries (Curtis Wright, Mercedes, some NSU).
With the leading plug where Mazda has located it, you really do need trailing for efficient combustion. Turn off the trailing, and you blow a fair amount of unburned mixture out the exhaust (which they used to do to facilitate "external combustion" for emissions control).
