I have no experience with this setup. As I understand it to help make the shift without the clutch, the throttle is effectively blipped while the shift takes place to interrupt power output.
What I don't understand, why is this blipped action not instigated by an ignition control, maybe mounted with a simple push button on the gearshift, no foot action required, and high rpm engine air flow never gets disturbed.
Seems simple to interface with an EFI system, and likely not hard to set-up with an aftermarket ignition.
What am I missing?

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
