 > There are a few fingerprints that are still in the legacy hex format,
 but their space usage is insignificant compared to 6000 relays.

 you are very quick in response. i see microdescriptor does not affect it.
 i have looked into my cached-descriptors and found about 2200 family lines
 with containing 23.548 sha1 notation fingerprints = 941kB. base64
 encoded, without trailing =s could result into 635kB only
