xSTILLFLY: How would that even work?
Well, the way it is now, it's too easy to just post a couple of bad scores to inflate your average before you enter a 'premium' tournament (as shown in the score history posted above). By making tournament scores worth more in your average than a regular ranked round, it would make it a lot harder (not impossible) to manipulate your average this way. And it would be a truer representation of how you normally play when there is something on the line. Being a tournament, it is also less likely that a person will turn in an outrageous card, because there is actually something on the line.
By having regular ranked rounds count at all allows those who are just starting or cannot enter anything but free tourneys to still progress in the average, it may just take more time (which I don't see as an issue because tier progression is too fast anyways!).
As far as using only 10 of the last 14 scores, this only aids in the ability to sandbag. Again if they were to use say 30 out of the last 40 rounds, and drop the bottom and top 5 scores, then the average is much harder to manipulate.
*edit* you could also implement a maximum score submission of say no more than a certain number of strokes above your current average.
But this is just a concept, WGT will address this issue as they see fit. I'm just throwing out ideas, trying to help.
P.S. this will probably also help with the reverse sandbaggers too (aka quitters)
xSTILLFLY: I think every hole should count as a stat, regardless of quitting or not. that way if they do good or do bad the stat will stay
Sorry, but this does nothing to deter the issue of sandbagging being discussed in this thread. In fact it would probably make it easier.
