Perf and KMH Delta Demo here:
This is my Performance Delta app that I created after feeling like I could not trust the delta values being provided by AC. It has a few extra features, as well. It is tyre compound aware, so you won't compare a lap on super softs to a lap on mediums. Any better time is shown in green, any time within .25 seconds is yellow, within .5 seconds is orange, anything over .5 is red, and it turns purple if all four tires leave the track. The color will dim if you are trending towards a worse lap time, and brighten if you are trending towards a better lap time (regardless of your up/down). Some of the features are adjustable from the settings.ini, which is created with default values the first time you use the app.
If you have any comments, questions, or suggestions please post in this forum.
