Granted, there are differences, and "Rules at the discretion of WGT" is more precise.
But there has been no move at all by WGT towards this subject, and to see it like I explained maintains the logic of this virtual world.
I don't see them putting any effort into practice rounds(!) where there's hardly a revenue. Which impact would this have, except of taking away XPs for spared shots?
I won't comment on your other proposals to bend the rules which might easily lead to new customer complaints, and the missing practice facilities have been explained ad nauseam by WGT.
Only one thing: The information about our virtual putts beats the pants off the information available on a real green: Precise length+elevation plus the exact power of our putts should guarantee a perfect lag shot at least. Furtheron, the slope indication is from another universe. Do you think Steve Stricker would have misread his penultimate putt at the Ryder Cup by four feet with the WGT grid?
