Well, since I am a gentleman here is my opinion.
Video explores the concept of "what MINIMUM round capacity is enough for civilians to carry around
without risking their safety in a self defense situation outside of their home or business"...
Then he goes in to the statistics to point out how many rounds ever needed for a self defense situation by civilians.
He is just pointing out that the statistics indicates that it is a very, very slim to none chance that a CCW will ever;
-involve in a situation where a gun will be needed for self-defense,
and even if that situation arises;
-just presenting the gun will solve the problem most of the times,
if the gun's presentation wasn't enough to stop the threat and the gun has to be fired, again;
-in most of those cases gun was fired only once...
and if one shot didn't end the situation, in very extremely rare cases;
-a maximum of 3 shots were sufficient to end the self defense situation.
So based on that data, his conclusion developed as "you'll be ok if you are carrying a 5 round revolver".
Somebody above mentioned very correctly. If you have to reload (no matter what capacity of a gun) you are NOT in a self defense situation. You are in a gun battle!
So, this video presents an opinion that carrying a 5 round capacity revolver is sufficient enough for a CCW without risking safety in almost every self defense case.
He is just making that point! That's all!
Again, not a rule... Just a point!
You carry whatever make you feel safer. Agreed!
The point is, if you are carrying 10+1 in the gun and another 20 rounds in two extra magazines, it is just because that's what make you feel safe, otherwise NOT because most self defense situations require 15-20 or even more rounds to be fired!
The message I got from this video is, any CCW out there doesn't have to feel unsafe IF not carrying a 17 round capacity semi-auto with 2 extra magazines.
This may be a controversial issue over here but I agree with the point he makes!
