It's just odd to not test at the given crank length relative to your inseam and total height as a starting point and then perhaps going even shorter depending on mobility. Cranks too long and there is no correct saddle height as you're too low or too high. In other words, you can't fit someone on cranks too long. If something isn't correct, you'll get the imbalance as the compensation strategy will almost always favour a side. How this presents is very different for people. You get this anyway a lot of the time even setup ideally, that's human biomechanics. People seem to understand about bike size, as in, I'm smaller, so my bike is smaller, but they can't make the connection with cranks. It's part down to companies supplying the bikes.
It's why I ask about inseam. I don't even need to see you on a bike to know what your starting point would be as an ideal safe max length. What I can't tell you is if you would be better going even shorter. Lots of people, particularly on mid and small bikes are on cranks too long.
Maybe, but be aware this wasn't my first fit with him, along with being already on a bike he had fitted for me 5-6 years ago and we used to ride semi-regularly together (when he worked at Local Bike Shop I use). This wasn't all 'measure me for a new bike' as he had a starting point - but really a check of my current fit alongside advice for what frame size should I get for a new bike.
I get your point about cranks, especially for those of us 'not-quite-normal' (ha!). Being around 5'7" I've always been slightly below 'normal' height (around 5'8-9"?) which is why I was quite conscious about riding a 54cm frame being correct for me. I was almost convinced it wasn't due to my shorter legs... But fit confirmed a 54cm as best. He did say I'd easily fit/ride on a 52cm but nothing to gain from doing so (for an aero road bike - maybe an all day comfort/tourer it would be). The modern trend is putting more and more focus on the pedal stroke. I guess we're learning through efficiency in the pedal stroke being equally as important as power when it comes to rider comfort/progress. Especially for recreational riders. 'Spinning is winning'!?
I didn't say he hadn't checked things - height is something I can quote (172cm) but Matt did check it. Although we didn't specifically measure inseam (mine is around 78cm - does that sound right?!), he did measure inside of knees to pedal spindle so figure that's really the same thing... The first hour of the fit was assessing me on my current setup in various positions (2 bikes) along with replicating that on the RETUL machine before changing anything. The next part was mobility/flexibility off the bike, checking mobility and tightness of muscles while discussing injuries and pain(s). More physio than fit, he identified tight hamstrings both sides (although said that's very common of every recreational cyclist he sees), with the left being tighter so confirming what he'd spotted on the bike about leg length (sent me a bunch of YT videos with exercises to do). Next step was back on the RETUL measuring things and making adjustments. Adjusted cleats slightly - commented they where mostly ok but my pedal stroke very square to the bike (although I'm slightly 'duck footed' when stood). My knee angle was 'very good' with barely any lateral movement. Changed cranks to 170 as a definite & obvious 'easy win', video again to prove ankle angle was better in the various parts of the pedal stroke. Then tried a cleat spacer on the left and it actually made my pedal stroke/angles worse (he seemed surprised by this so maybe it works for others).
