Can I ask if anyone would ever advocate a ground run being performed via a very low speed reject when performed by the pilots at an outstation? i.e. Immediately after the aircraft began to roll.

This is the procedure we used at an outstation and I was somewhat gobsmacked when I was told during the taxi out that the brakes would be released then the TOGA button pushed before an immediate reject performed. The objective was to test if maintenance work had fixed and would prevent re-illumination of the COWL ANTI-ICE annunciatior (due faulty valve / over pressure from 9th stage) when Takeoff thrust was set............previous day we had this condition, rejected and then stopped for the night.

I would have expected simply to apply Takeoff thrust against the brakes as opposed to performing the low speed reject. Was the low speed reject inappropriate? Could we have done this without brake release?
