There is zero science in there.
Having seen first hand Vitus bikes with bonded tubes that have popped tubes while being ran fixed, I just provided @JoeGW with some unsolicited advice.
I am sure you have the actual software to show the areas of the BB / chainstay that are under load when you do a mad skid!!!
Since it is a family heirloom, I image he'd prefer to keep it in one rideable piece as long as possible.
Ooh, I feel science coming up. Please show your working.
