My reviewer asked me to prove that my new challenge cache needs to be attainable by a reasonable number of cachers (around 20 in the area). This is refering to the guidline saying
“A challenge cache needs to appeal to and be attainable by a reasonable number of cachers. Your reviewer may ask for a list of cachers from your area who qualify.”
How can I check and prove this?
The challenge is: „Find at least one cache in each of the 28 EU member states“
