Qualifying Practice Program to Difficult?

@Apophis-STR, yes, I agree on 16 races being the sweet spot! And as much as it's intriguing a 10-season play, I find the range (that ultimately consists of fractions of seconds) that you gain or lose with performance scores of the team wouldn't scale sensibly over ten years. Probably, you would barely notice the difference, and my inconsistent skill would make it hard to feel it.

I would love a 9-12 year play if, every 3/4  years, we get to fully re-design the car with some hard reset of upgrades.

You would put some money away every year for future car projects, hire some mechanics with different characteristics, and direct the focus of the future car team in some interviews (similar to the first one at the end of the year). 

So practically, you reset cars every 3/4 years, and the new car is a result of the current car performance plus the money invested during the year in this project, the eng that you hired specifically for this task, and the interview you made each end of the year, plus some random factor (similar to success/fail of parts) - it would be nice to have different skins of the car to pick between 

That would keep everything fresh for a lil longer. It would be like restarting a career every 3/4 years. That is what I already do practically.

But I will try to start a new career with 16 races (full simulation) in parallel with the 23 races (5 laps race) I am halfway through, or maybe I should wait for the first couple of patch-updated ones so maybe they fix some stuff in the meanwhile.
