Example on the 13th Feb, the only additional cost to me on that day was a £2.34 cost which was the peak rate differential for one half hour slot. All normal cheap rate for the standard 6 hours was shifted and concentrated into the 3 hour in day adjustment slot.
Reward was 38,508 points including 100 bonus points or a £48.14 rebate.
Probably only two more test sessions left for this season.
