And so this thing is like 365 degrees.

Yeah.

So it's like a one to three 65, let's say zero to three 65.

Yep.

And you, let's just say you break this up into 10 different, uh, uh, severities.

You're already, uh, even with just this oversimplified model, your action space cardinality, right.

It's 365,000.

So that's like,

a hundred X bigger than alpha.

It's in fact, it's about the size of the example or a decent amount smaller than the size we said, which is break and CTS.

So there's a, you're saying there's a decent number of these that's from like dash cam footage on YouTube or something, but not really that many either.

This is, this is a sequence of what you're showing here.
