True the Vote themselves used 100ft as their standard of 'visiting a box'. Says who? Says the GBI
"According to a letter obtained by GPB News, GBI Director Vic Reynolds said that cellphone data provided by Texas-based True the Vote that allegedly shows 279 cellphones that were tracked multiple times within 100 feet of an absentee drop box alone was not evidence of a crime."
The GBI director wrote "an investigation is not justified" after reviewing the claims.

So someone driving by a library with a ballot drop off box was counted as 'dropping off a ballot'.
