TMs Question

My first ever raid was a level 1 and I got 2 rare candies and a charge move TM. I assume you can get quick move TM's as well.

I completed 20 raids, so far.
7x level 1..........1 TM charged
7x level 2.........0 TM
2x level 3.........0 TM
4x level 4.........1 TM charged

I've done about 7 level 4 raids and have received 4 Fast TM's and 2 Charged TM's (The first raid I got 3, but often none). Also around 5 raids Levels 1-3, but I never got a TM in any of them.

My second raid was for a Magikarp (Cp ~1K). Got a Fast TM, 2 rare candies, some other stuff that I don't remember well. So yes, even the simplest raids can get you a TM, or at least got me one. But that was one of the first days, they might have tweaked the rewards some for raid level.

1st 3-4 raids (level 1-3) got 2 charge, 1 fast TM, then last 4-5 raids (level 1,2,4) got none! I guess TM may not be that many as we originally thought!

I soloed a level 1 earlier this evening and got one rare candy and two revives. From now on I'm only using my raid passes for levels 3 and 4.

1 level 1 .... 0 TM
4 level 3 .... 1 charge TM
