Good to meet you, Roberto! Strong work!
I'm a few days in now, and I'm really enjoying the app. The exercises are challenging and gamifying them by keep score is motivating to use the app more to try to improve. One other convenient feature of the app is I used it to troubleshoot my Fanatec CSL load cell brake pedal which I suspect has a bad load cell sensor.
I have a small YT channel and it's on my list to do a video on the app soon.
I have one braking exercise suggestion... A few months ago I used ChatGPT to create a web page to help me learn brake pressure and it might be worth considering something similar for your app. The page has a start and stop button and a 4 minute timer. On start, the page displays and uses a synthetic voice to shuffle the values 10, 25, 50, 75, and 90 which correlate to brake pressure. The app calls out a new value every 7 seconds or so, I forget the exact value.
When a value is called out, I try to hit that pressure on my brake without looking, then glance up and if I got it right, I hit the space bar to record a point scored. If I got the pressure wrong, I do nothing, no point scored. The app then tracks my accuracy until the timer is up.
I thought it was an idea worth mentioning, but no worries if it's not a good fit for you.
