Looking over my own records for GeoffLems, some of them improve on yours:
Tricky 18 "Fort Lemmington" 49/50
Taxing 17 "Lemmington Abbey" 39/40
Taxing 29 "Hangar B" 17/20
Taxing 30 "Tabula Rasa" 76/100
Mayhem 3 "Topsy Turvy" 48/50
...and I was inspired to have another look at this pack and found the following improvements:
Tricky 7 "Mining Workforce in Decline" 30/30
Tricky 12 "House of Pancakes" 97/100 (improved to 99/100 with the help of WillLem in discord)
Tricky 19 "Wire Cutters" 24/30
Taxing 15 "Mutiny on the Bounty" 60/60 (with the help of WillLem in discord)
I think that's it as far as Fun, Tricky and Taxing are concerned, but I don't know about Mayhem as I haven't even solved most of these yet
