Toe overlap fall: 0
forgetting to unclip fall: at least a dozen.
Got my first "proper" road bike last summer and started with clipless pedals right away; on the first day I rode I almost fell but was saved by a friend, since then never had any issues... The guy I bought my bike from told me to always get out of the seat when slowing down or coming to a stop... I suppose you can forget to do that too but do it a few times and it will just become a habit. I don't necessarily do that everytime now but at the begining I'd say it was useful and perhaps was a factor in avoiding the falls... I don't know.
