Of the 270 retailers who have completed the 24-week SIP course, only 26 have boosted weekly sales to hit a target of Â£1,400. Some 148 terminals have so far been removed and reallocated.
Data for the month ending October 31 reveals 41 retailers put in appeals against Camelot's decision to take away their terminals. Seven were upheld.
Camelot is to target "cash rich, time poor" Air Miles collectors to take out direct subscriptions, bypassing the retailer channel altogether.
It is offering up to 250 miles for a Â£6 a week spend.
