e calculator is bigger, which means we need to go higher, try 110000 feet,, and we now have 0.006832, Opps too small but close, try 108000 feet. and we get 0.007474, for me thats close enough! you can whittle it down to an exact number if you wish but I'd stop there.
ahh what the hell huh,, 108250 feet should be the predicted Burst altitude!
So with this set of parameters for this flight I would state that the balloon will burst at 108,000 feet.
It's been for almost every flight spot on less than 1000 feet off ever.
