What I meant was that within those 3x are the random chase figures, similar to when Clone Trooper (4x) contained a 1/24 Gree.
I thought this was the breakdown for Series 10:
Clone Trooper 4:12 (Really 28:96 with 4 chases per 8 boxes)
Darth Vader 3:12 (No Chases)
Grievous (Reg) 2:12 (Really 15:96 with 1 chase per 8 boxes)
Palpatine 1:12 (No Chases)
Anakin 1:12 (No Chases)
Tarful 1:12 (Really 7:96 with 1 chase per 8 boxes)
Easy Chase: Gree 1:48 (Found in the Clone Trooper Boxes)
Hard Chase: 4-Arm Grievous (Found in the Grievous Boxes)
Hard Chase: Tion Medon (Found in the Tarful Boxes)
2 of the chases were in shorter packed boxes, but agree with you that it was nice to find the comon chase in the 4x Clone Trooper boxes.
Based on S10, I'm going to guess the following for chases:
Easy Chase: 8D8 in the C3P0 Box (or EV-9D9)
1:96 Chase: Malakili in the Luke Jedi Box
1:96 Chase: Ree Yees in the Amanamin Box
I'd love to get a Ree Yees, Squid Head, or Oola in this set. Klaatu, Weequay, Barada, or Nikto would be okay with me too. I could live without Malakili, 8D8, or EV-9D9 though.
