You're very welcome!
Yes, but my opinion is even more radical. I think showing "difficulty" (whether it's number of leading zero bits, number of leading '0's in hex, or number of leading 'q's in bech32) is not ideal since something with 10 zeroes looks half as hard to generate something with 20 zeroes (or '0's or 'q's) when, in fact, it is 1,000 times easier to generate 10 zeroes.
On https://powrelay.xyz/explore I show the number of hashes needed (on average) to generate an event with that many zeroes. An event with 10 leading zeroes needs 2**10 = 1_024 hashes and one with 20 leading zeroes needs 2**20 = 1_048_576 hashes (on average).
