Shun the frumious Bandersnatch!
I'll put it like this:
The difference between the worst backers and the best basket isn't as big as the difference between the worst tees and the best tees.
If the tees pads are merely, decent, improving the baskets makes sense. But if the tees pads aren't level, or just suck, don't worry about the baskets at all... fix the freakin' tees.
Worst Baskets to best is huge and some courses I have seen crap baskets that should not fly anywhere in the world, they used 12-15 baskets used to be a 17 basket course where tee off 1 was originally basket 18 as they did not have tee spots at all for course. For baskets they made them out of 95% wood very small micro chain like that from a cheep chain necklace for 9-12 chain strands taking word Chains literally and the plastic landscape divider stuff that keeps lawn from entering planter beds. The baskets were never upkept and some you had to layup right next to the basket to carefully put the disc in the basket so carefully that in some we just took the disc put it so to PDGA rules the disc is in the cage area in the basket but still in the hand. Yes this is/was a semi public course in the Fingerlakes area of NY, the baskets were used by a local kids club who claimed to own the land or at least the baskets but let people play the course as long as they did not disturb the kids club. That Course lacked tee off areas so we used basket to basket but did have a marking on a post of a basketball hoop pole in sharpie saying hole one tee off, so sometimes when the court was in use you had to tee off standing in line with the pole but off the court and no runup allowed. Course was tough due to baskets mostly but for some reason they thought a single 550 foot hole was appropriate for what was other then that a total beginner course where I used mostly midrange and putter on. We had a map from online printed out for the course layout with distance on map all thanks to a cousin or we would have been lost looking for the baskets.
So yeah both can be very off with lowest basket to highest end. Then also very off with the tee area from a worn out natural no tee area using previous basket/target as tee marker to the best concrete one. This is why I did not vote as both need to be at least decent for a course to work as a public or open to public course.
