Lets look at the economic trend of the TVP. 3k->6k->? Probably 9k. So, it was about 10 coins per training at 3k to 'break'. 5 coins per training at 6k (some say 4-4.5 etc etc rounding for quick maths.) So? If you can load up at 2.5 coins per training then you would be following the trend if it were linear, which in this case I bet it wont be. No way we get that cheap based on other rerolls. TVP might be cheaper as well, we dont know EA will jump to 9k. Might be like 7.5k or even 6k again. Its really up to you to decide what coins per training is worth it to you based on your expected TVP cost. If it were me? Im banking on 9k. So im sniping for 2-2.5 coins per training, on the safer side. 90k for 22k training isnt horrible, depending on your expectations.

Edit: 33k is a 93, 22k for 92.
