Odd Charging plans

[AGLAISTER]

Describe the bug
Charging plans are often selecting more expensive slots to charge when later cheaper slots are available including where negative slots are available and then selecting a slot where the cost is postive

Expected behaviour
Cheapest slots for charging are selected

Predbat version
v8.7.2

Environment details
GivEnergy Gen1 Inverter and 9.5k battery
NuC Home Assistant - all up to date (core, supervisor etc)
Octopus HACS latest

Screenshots

As can be seen from the screenshot at 21:35 the plan chose to charge, SoC in screen shot 1 was 53%

Screen shot 2 shows it charging SoC 60%

In both cases it can be seen that there are later cheaper slots, 00:00 (14:11p) and 02:30 (14:49p)

If applicable, add screenshots to help explain your problem. The most useful ones can be your battery chart, the Predbat HTML plan and your current settings in HA.
