I'm absolutely not a Flo Jo expert, and don't have all data sets at hand in any case, but all-athletics does list these indoor times for her:
50m ind. 6.32 Rosemont (USA) 16.02.1986
200m ind. 23.13 New York (USA) 22.02.1985
I have no other information on these meets (actual venues, results, etc.), but perhaps some dedicated Historical forum reader with access to lots of historical data (I know you're out there!
) can post something to add to to this.
