per tx

so you're saying if you got 10 100k transactions you'd prefer treat them all as tier 2 instead of tier 1?

Yes. At least within the scope of the threshold. Active attackers will per their job description fuck you if you don't have cumulative controls.

For simplicity, pleb people amounts:

100k = 1
500k = 3
default = 6

So 100k = 1 means 100k cumulative in the current block can go through, everything after that goes into tier 2, until 500k, requiring 3 confirmations, and everything after 500k in last(3) blocks goes into 6 confirmations. Could probably live with just the first and default tier at 3 though

This means that at current orphan rates I'd risk 100k per ~month.
