OK, so I did some more research on the subject of Pindari raids in the Madras Presidency as has been described by Oakes and Robertson in their 1817 report (discovered by me BTW).
What I have further discovered not only buttresses my argument but also soundly refutes OP's counter-argument.
Elated by their success in this raid and determined to raid across the Krishna into the Madras Presidency, the Pindaris' planned a second raid. It is this raid that became the subject of Oakes and Robertson's 1817 report.
This raid commenced on the February of 1816, a second party of about 10,000 Pindaris' once again crossed the Narmada from North India and took the same route that the first party of Pindaris' had taken. This time the Pindaris' were successful in crossing the Krishna.
Most of the Pindaris' recrossed the Narmada by the 17th day of May, 1816 and returned to their residence in North India laden with their ill-gotten gains.
