I think this has been lost to time. here is the last time i tried to find it:
Here is where Gendgi quoted it on the old forum
In a since-deleted post, @NianticCasey-ING offered guidance regarding tennis courts at a park. There were maybe 5 or 6 separate enclosures that were maybe 20-50 meters apart, and each enclosure had 2 or 3 tennis courts. The advice offered was that each fenced in enclosure could be eligible on its own, but individual courts within the same enclosure should be duplicated. Since that was “pre 3.1 refresh,” it’s unclear if that is still accurate or not, or if it is considered an unchanged “definition.” It was deleted at some time, likely when @NianticGiffard was purging threads.
And this is where Roli quoted it as a fact
In my experience, here in the US, separately fenced courts tend to be accepted separately.
