I haven't uploaded anywhere close to all my satellite contacts to Logbook of The World, but I uploaded enough to get 100 grids as of yesterday when WW8W confirmed our contact from 2018-06-17 on AO-91. He was in EN73.
Thanks to everyone else who worked me. Clayton W5PFG got me the most grids at seven, and Gabe AL6D got me five, using almost as many callsigns! (NJ7H, NJ7H/VE3, NJ7H/HR9 and KM4RTS [I was too far from my QTH when I worked him in AK as AL6D]). Honorable mention to the rest of the folks that gave me more than one grid: WE4B, KM4LAO, WD9EWK, VE3HLS, KI4RO, KE0PBR, and AA5PK.
Here is the full list:
