My prediction software comes up with .019 sec/100 ft, which is pretty close to your 50 ft/ .01 sec number. The software shows a really good prediction line with the data your provided so I wouldn't worry about it too much. See the attached image.

The other two runs yield a ratio of .030 sec/100 ft.

I could see a smaller engine being more air sensitive. A relatively small change is going to mean more with a smaller displacement engine than with a larger displacement engine.

Again, if you seem to be coming up with the same ratio all the time, don't worry about what other guys have. Based on the numbers you provided, it looks to me like you have a pretty predictable combo.
