That's a great improvement. I appreciate tips like this. I prefer using UV curing resin (the kind used for windshield crack repairs) as opposed to super glue for leveling inserts. 2-3 drops is all it takes... It is tricky to get it to flow with no bubbles but, practice makes perfect with all these things. Also, with that method, if you mess an insert up, you can peel it away fairly easily and try again. Also, you can usually get decent results without removing the inserts from the PF.
