I'm at lvl 25 and just got an 18 yo AMC with 98%. Wage was 109 M (according to the table 110M is the max but I haven't seen one yet) with 28.1 M Wage.

So I thought he is a fast trainer and took him with 35 tokens from the Auction (which I think it's fair, not cheap, not much).

In your guide it says that a fast trainer needs about 50-55 greens to get a SA. However, the Shadow Striker SA had 50 sets whilst the others all had 40 sets. When you said 50-55 greens, was that for 40 sets or 50 sets?

I used 75 greens to get him SS ability (50 sets). Does that make him a 2nd level fast trainer or is it normal because it's 50 sets instead of 40?
