just to let you know about another of my experience...
http://100stamps.club/stamps/SI-488
I received a letter from user Olga (by the way - same name & same wishes, but different address I already sent and got 5 for sending MINT CEPT 2018)
stamps were poor, bunch of definitives, Russian ones glued together, cca 10 % damaged, etc... and on cover reused russian definitive stamps. But I gave 4, because ammount was ok and because i hate to go lower
I made an experiment - I switched just damaged stamps and I sent back, what I received...
and guess what!
I got a 3! rating
Some people are their own enemies and they have double standards
Shame on you Olga
