OK then, lets walk through the math. I'm sure it will be riveting.
0.080 / 0.055 = 1.4545 i.e. a 45% difference in density.
square root of 1.4545 = 1.2060
You got me, I should have rounded that to a 21% increase in terminal velocity given a non linear squared drag function. Why did you think I was talking linear? A 20% increase is the difference between 40 and 48 MPH, that sounds significant.
Do you have a different answer for the increase in terminal velocity based on the density changes you mentioned? You seem certain 20% is wrong. I'm not trying to be argumentative, nor am I in a huff at having my math skills questioned (well, maybe a little), just wondering.
