Cheers all!

Close to half, yes... I gently move the lever down until I feel slight resistance (mostly at around 30-40% of the way), then slowly lift it up again to get more water hopefully without damaging the puck and gently move it down again until I see first drops (which was especially easy with the screen of the 600D facing up this time!). Depending on the coffee and current theories or moods I then apply different pressure profiles. At the moment I feel that starting slow is good... So I leave the water in the coffee for as long as I can by very slowly increasing force in the beginning. As soon as a the flow increases (about 10-15s in) I go easy again to maintain an even flow rate.
At the moment, I'd say I pull about 25ml from 20g of ground coffee, with a very long, say 10-15s, active preinfusion ('active' because it's not just boiler pressure but roughly the weight of my arm on the lever), 5-10s of properly pressing down the lever and then 10-15s of decreasing force. I shall set up my iPhone as a second camera some time soon to do a multi-perspective study of this!

Excellent! It seems like the relative few that are out there, are owned by this forum.

You were able to casually monitor your distribution while dosing; placing even amounts of coffee in the small basket. With my K10 - the dosing vains fill completely with grounds giving me much larger "drops" of ground coffee. If I'm off a little with the bigger "drops" of grounds, my dosing can be uneven. While you often hear bragging about quick grinding speeds around Home Barista, I think there is a value to slower grinding that is understated.
I never really thought about this, to be honest, but you may have a point. Sometimes, when I'm lazy in the mornings, I let it grind for like half a minute while I go gather my cups and throw together breakfast. And right now, I feel certain that those shots are not as good on average as when I constantly pull the mazzers lever like a lunatic. This requires investigation!
