Reading the benchmark script, and the explanation of it at github, I think the deviation is there to account for floating point artifacts. I.e. where JS = 0.01499.. and GPU = 0.01500.., that's fine, but if the numbers (read results from the fractal function) are deviating more, that's an error. Edit: Actually, "(JS: 0.56, JS&Turbo.js: 1.74)" seems to be a valid result from what I've seen. May just be that the chosen deviation value is an unfortunate edge case.
