I am not saying that people shouldn't enjoy their 300 when they bowl one. & I think that is where people get mixed up when these sort of discussions come around.
For people to take insult to reality is just plain laughable. Reality is, technology in this sport has advanced so far that we can manipulate the sport to make it easier, or harder. In easier cases, we can lay down an oil pattern that gives a 5 board area to shoot, so your ball makes it to the pocket. We can also make it harder by laying down a pattern which demands the bowler to hit one single board dead on every shot, & to put the ball down in the exact same part of the lane (for fear of leaving a 10 pin, etc)
Everyone should by all means, value & cherish their perfect game. You bowled it, good on you. But when it comes to 'actuality', your 300 may have very well been an easy 300.
