Mac,
With all due respect, that simply is not true.
If you do some research on single trigger design right back from the beginning of it's use with double barrel rifles and shotguns, you'll find that there has always been a problem involving double discharge due to the shooter.
The problem was/is called "involuntary second pull" and it involves the shooter tightenening his grip during recoil just after the shot is fired, hitting the trigger again in the process, and accidently setting off the second barrel.
Pretty well all the better makers and manufacturers were well aware of this and many/most designed and incorporated some type of mechanical device in their single trigger systems in an attempt to prevent this particular type of double discharge from happening.
Many shooters perform this second pull without even realizing it, as it will not cause problems if you are shooting bolt actions, single shots, or doubles with 2 triggers.
However for these guys it can show up quickly with (some) doubles which are fitted with a single trigger.
You don't need to take my word for this though, because if you do some research on the subject you'll find plenty of information available.
One thing that often causes it IMO is where a shooter has a loose grip with his trigger hand, and a feather release on the trigger.
I know a guy who had been shooting big 2 trigger doubles for 20 years with no problem, who double discharged a big single trigger double every time he shot the thing.
Heaps of other guys shot the same gun without ever causing it to DD.
That was 18 years ago, and the gun has never caused a problem for anyone other than that shooter, and it just so happens that his technique was a loose grip and feather trigger release.
That instance is NOT the only one I know of regarding single trigger DD due to feathering the trigger pull.

99% of the time, if it happens, the prudant thing to do is open the rifle, and fix it, because 99% of the time the offending lock is not holding the sear engagement properly.
99%!
Honestly, IMO I think you've just pulled that figure out of a hat.
I fail to see how any one person can speak for 99% of all the single trigger doubles on the planet, and for 99% of all shooters using them.

If, however you ignore it and try to adjust you techneque, and you have a DD, or a AD and someone gets hurt, then what?
If you read my post again you'll see that I've already mentioned that yes, there is always the chance that a mechanical problem could also be the cause.
I did NOT say to ignore the possibility of a mechanical problem.
My post was saying don't ignore the possibility of the shooter being the cause of the problem.
To say that it is almost impossible for shooter technique to ever be able to cause double discharge with single trigger double rifles, is ignoring the well documented fact that gunmakers have been aware of for a very long time.
