Mod 29 -sorry if I messed you up by adding an unnecessary question but I do think there are things that may have been ruled out by 19 that weren’t ruled out by 17, so I’m not sure if it’s fair not to count it.
In any case, I have to leave for Shabbos soon so I hope we get the answer by then, cuz otherwise I’ll have to wait till after Tisha B’Av for the answer!!
