If a blogpost has a title suffix like q[#_2] or q[ %2 ] or q[w1r2], that means

“Reviewed, refreshed, possibly revised, 2 times, not counting the initial posting”

Q: how is this different from t_w1r3?
A: I can’t have w1r4, w1r5, w1r7 ..

Q: should this count tally with the wordpress revision history at bottom of blogpost editor?
A: No need. That number is often double-digits
