*No ball-by-ball data on ESPNcricinfo for the innings in which the player brought up 1,000 runs, therefore only a range can be given based on the total BF during that innings.
** Deandra Dottin, Stafanie Taylor, Mithali Raj and Harmanpreet Kaur all played in the 3rd T20I between West Indies and India at Roseau on 22nd February 2012. For some reason, the available scorecards for this game have no balls faced, boundary data, etc, so an accurate BF count for their respective careers can’t be reached. This is why, for example, those players have no T20I SR listed on their respective ESPNcricinfo profiles.
In terms of balls faced, Dottin is likely the fastest woman to 1,000 T20I runs (her first 1,000 runs for which there is available data came off no more than 744 balls, and she only scored 16 runs in the innings at Roseau).
