I don't know if I can even answer this there are so many. Plus I was a staff writer for a SAG-AFTRA audio drama company working on scripts for them. Then my own stuff, 4 years e-columnist with one magazine a few years with another, copywriter for an ad firm creating mini stories even smaller than flash fiction, then flash fiction, etc. etc. I bet I'm clocking in at around 400? Maybe less maybe more.
But... I'm also older than a few of you sooooooo
And when you really look at it, it's not the quantity that is important, it's the quality.
