That would not be statistically significant. All your test would prove is I stop better with a brake. I know this, that's why I use one.
Evidence fail. If you did it with 2000 people, that would be more like it, but I'm not a statistician so I couldn't give you the actual figure.
Get your own evidence. Do a series of brake tests (down hill, emergency stop, slowing for car/corner etc,.) with your current setup and then remove the front brake and do them again.
If you cannot stop as quickly and effectively without the front brake then you have your evidence. Whether any increased stopping distance would cause you to actually have an accident is irrelevant, but the potential for accident would be higher, therefore it is more dangerous.
That wouldn't be evidence.
The sample would be 1. Me.
