it should be clear if it's sagged or static, and with what fork, but forks vary by 10mm between brands so there's 1/2 a degree variance.
add in the fact that framebuild tolerances mean batches can vary by up to half a degree and it does make a bit of a mockery of HA obsessions.
I've seen mags test quote 4 or 5 bikes in a test (one of ours was included) and there was no mention of how they measured them – if they actually did. the figs varies a lot from what they should be and our bike was said to feel nicely slack, but they listed it as 70 degrees – and a better ride than a bike that was listed as 68-69 from memory.
it's hard to use printed HA figs to compare bikes between brands unless you know what fork length the angle was measured at, not just the travel. fork length cancells out brand variations, so what you need is "68 degrees at 520mm" etc to make comparisons.
weight distribution and front-centre also affect the handling feel in a similar way as head angle but no-one seems mentions that very often, basically it's all interlinked so you need to ride or measure the bike to really tell and that's the tricky part.
