Is SRD Battle Status Customizer above or below the Odometer Gauge plugin? Does behavior change if you flip the order?

No, this is not correct, unfortunately. Please use the backup and change those lines to what is pictured here (highlighted in blue):
Basically you are trying to replace the 0.75 values with the value determined by the plugin parameter. Once this change is made, please save the plugin and run your project. I have tested the solution out in our sandbox with SRD Battle Status Customizer and it should do the trick.
