Export Before Off-Peak Rate Stopping Early
Describe the bug
The nightly export before the start of the next off-peak charge period is stopping the export early with 16% of the battery left instead of the normal 4% SOC keep.
Expected behaviour
This has been working fine but intermittently it changes the plan and stops export early. Should export down to 4% as was working consistently on v8.18.12.
Reverted back to v8.8.12 for now as it is a more stable version (see below screenshots).

The reason is the two plans are almost identical, one exports more earlier but then that will mean less export during the cheap period due to more charging time required.
Seems to change its mind. Some days it’s correct and sticks, other times it flips. Earlier version tends to stick better than latest version. Previous versions always exported earlier down to reserve.
The point is it doesn't really matter which way you go, if you export down to reserve you have to charge more, meaning less time to export during the cheap charge period. At the end of the charge period the cost is the same either way.
