Little finger on what lever length??
Little finger on a 10m lever = a lot of force.
My rule has been finger tight using the short end of an allan key, this really isnt very much force as I work in an office and have ladies hands. I supposed I could have used my little finger on the short end of an allan key, or perhaps just used the weight of the allan key itself to tighten the bolt. But I would argue in his scenario your not actually tightening the bolt! – so whats the point, you might as well have quick release and a floppy front wheel.
