Note from Punko. Heat uses the , as a delimiter to separate values High , Low
Example; fspoiler_lift -.31, -.36
Front wing adjusted to minimum is -.31
Front wing set to max is -.36
The comma is a delimiter to separate High and low values.

(note: HEAT WC cars add tape to reduce drag and increase front down force at the cost of reducing engine cooling.
GT and formula cars do not have the same condition and adding front spoiler or wing angle will INCREASE front end drag.
The same remark for a GT or formula car would read more like this:
