Vink is a good pilot who has a very repetetive MO. I am pretty sure he could do lots of damage with the technique shown.
I watched a film where a bomber received a collision message. I did not see a film of 3 bombers being purposely rammed and destroyed as i expected. If it was that easy to destroy a trio of bombers in that fashion I would expect a film in fairly short order.
It isn't reliably easy to do because:
a) You don't know the internet latency of the enemy bomber (if you find someone to practice against so you know what distance to fly ahead/behind their bomber it will only be reliable against this one person).
b) To aim for the right point with knowing how far to 'lead' without being shot up by most bombers, makes the approach angle and speed very challenging, risking a collision to yourself.
