Just a complete guess on my part, and just as a general statement regarding equipment choices.
I would suspect that 'pros' utilize equipment wherein maintenance cost/effort are not a factor. For example.... I play with a hard tip. Not that a hard vs soft tip will give any more/less performance. However the hard nature of that tip allows me to play for extend periods with near zero maintenance on shape, glazing and provides consistent performance throughout it's life. The con of such a tip is the harsh feedback/feel. I have used my player with a soft tip and I thoroughly enjoy the hit using one in orders of magnitude more. I believe a 'pro' player will opt for that soft option, because time burnt changing and conditioning their playing tip can be perceived as an investment in their performance.
When I was chasing soft tip performance the shaping was continuous and replacements were no more than a couple months of casual play. Pros likely rip through them in a couple of weeks. If that long....
