I am not disrespecting you, your passion, or your hard work, rather to the contrary I tip my hat to you for doing what you do for I lack the time or the knowhow to do it and commend you for adding so much to the forum and all of our collective aero understanding.

To say a result of someone's work is "totally flawed" and not being able to explain in detail how exatcly "totally flawed" it is - is "totally" disrespectful.
There are many inaccuracies in those simulations and all of those can be graded and their impact assessed. Even with all of those inaccuracies combined, simulations
are very useful as they show a percentage difference in drag 10 times bigger than what teams are trying to chase and lower during a season. That difference is way beyond a margin of error and represents a conceptual difference in drag reduction. And having promised not to share details of a simulation verification from an F1 insider I got, I won't - but I did get it.
Anyway, the difference in drag is so large I can confidently say
F1-75 in this launch configuration generates substantially (more than 5%) less drag than W13 - coming from the substantially smaller airbox, smaller rear wing and rear tyre drag. Without the simulation and seeing the effects of different geometries on overall flowfield, I wouldn't claim this in my wildest dreams.
This is what I claim, not what I know. So anyone (including myself) saying F1-75 is 5% less draggy than W13 and stating it as a fact in the future (without actual data from teams) is wrong and shouldn't do it.
