Eagle TopRouter not at 100%

Any Eagle gurus here? :slight_smile:
Does anyone know why when using Auto Router feature TopRouter never reaches 100%, even tho some variants below it are at 100%? This makes no sense to me... Gotta be a reason... Eagle v 7.3.0

It never reaches 100% beacuse your layout cannot be auto-routed with the rules you set.

I'm not sure if you ready my whole post, but it does reach 100% at few variants BELOW TOP ROUTER... I'm just not sure what drives "top router"...

I use eagle almost daily, and have for several years now, just upgraded from 6.6 Pro to 7.4 Pro license - what is Top Router?

You don't have TopRouter? It's very top line in the list of Routing Variants... I imagine it picks best out of all other variants... See attached.
