It doesn't 'fix' it but instead does the /2 calculation. This can lead to floating point answers on custom ratings columns if "allow half stars" is checked.

The calculation is never done when using calibre's database interface, so the programmer can know that the answer will always be an integer between 0 and 10.

There was the Action Chains Scripts thread in the Plugins forum but I haven't seen any activity in it since September, 2022.

That is a good place for it. Thanks.
