It's not so much frequency for me as it is just ... if I go without clipless, I feel insecure. My feet come off the pedals a lot, I have to keep them settled on the platform instead of lifting my legs, etc. Technique is different, mechanical connection is completely lost, and it's unnerving.

When I first clipped in I thought it was awesome... the very first time, just amazing. After that I kind of don't much notice unless it's not there. I have the opposite effect riding without the clip-ins now, though. Just like when I switched from an automatic to a manual ... the manual transmission is easier to drive, automatic is unnerving and impossible to parallel park.

As for the pedals hanging or doing whatever, meh. My brain works out what's going on, my legs move accordingly, the cleat finds the pedals. The hard part is getting the cleat to actually clip in, which involves shifting my weight onto it... typically while I'm pedaling, if I don't get it immediately on take-off, and thus I'm trying to effectively power my bike but also trying to put power into my foot to lock a cleat into a clamp.
