[Closed] How on earth do you snap a chain?

Punctuating so many posts on here is the phrase 'then I snapped my chain'.

I have never snapped a chain.

1) I quickly clean and lube the chain within 2 days of every ride.
2) I replace the chain when it stretches to 1/16th over 12" (after 3 rides for the last one, albiet long races in mud)
3) I slightly ease up the peddle power as I shift and don't crunch the gears.
4) I don't cross up the chain too much and select chainrings accordingly.

All this sounds a bit anal but it's just common sense.

So what on earth are all you chain snappers doing? It's like broken chains are as unavoidable as punctures (ahem, unless you run tubeless :wink:). If you follow the above rules then surely they shouldn't break.
