Hi @Ben-And-Maoie0
It seems there are hosts on this forum who have all their historical host ratings on record and who can re-calculate their hosting average from those ratings (I've also tried, but I can't see more than a year's ratings). If they are correct in saying that they can calculate their hosting average exactly, it implies nothing else affects the host rating and that it's separate from the guest rating. Many of them are also confident that the host rating is a straight-forward average score with no weightings or adjustments.
