Thronebreaker sigil - how many 6-star shards?

TyEdge

I’m just hoping someone can check my math:

Test of the TB brings 400 per week, and trade-ins can bring up to 1500 per week, right?

A well-timed purchase gets access to 6 weeks of rewards, so that’s up to 11,400 shards? (You buy before the Monday reset, get all the rewards from the week that’s about to end, then you have 4 full weeks and 1.5-2 days from the sixth week)

I'm not TB so I can't check your math, but a lot of the trade-ins obviously require other resources to trade in. So yes, I will assume that you math is correct and you can get 11,400 shards, but you will need to give up other resources to get them.
