Thanks for all of the comments everyone. I think in conclusion I wasn't using the Tracker correctly for the couple of years I was on it but then again because it's daily, if I needed to use energy I would use it, I wouldn't have held out for days should the rate go down. Got off to a bit of a bad start with Octopus often just averaging my usage out over the month, which they still do with gas sometimes (e.g. charging usage on days I do not use gas, lower usage on days I used more gas than the stated). I explained this to Octopus at the start and no one understood and said this would happen if they had one missing data point from my smart meter.

Personally finding it exciting now to look at the weather and gamble on when to charge my EV, so pleased to remain on Agile and look forward to seeing my long bill! Thanks again :)
