We were told it was done to avoid crossover from having 7 and 8 fire consecutively....and replace it with 6 and 5 firing consecutively.

I've never found a difference in performance.

I seem to have the 1, 5, 4, 2, 6, 3, 7, 8 burned into my brain alongside my service number (old vets will get that, younger vets never had one)... but I've never managed to memorize the 351 version.
