The narrow slot in the bolt face for the blade ejector isn't as prone to brass flow as a plunger ejector and isn't a good indicator of pressure until you get *way* up there in my experience, but a draggy bolt lift is still a reliable indicator. With the pivoting handle installed there's no extraction cam at the top of the bolt lift so you can easily feel bolt lift drag and sticky cases.
Regardless of action, short of a strain gauged barrel IMO it's always more reliable using a blade micrometer to measure case head expansion at the 0.200 line on the brass as the primary indication of excessive pressure and a draggy bolt lift as a secondary confirmation to see if you're pushing things too far.
