Shorter sentence for the result statement without confusing plus-minus sign

I just realised that using the plus-minus sign can be confusing, because it is usually being used for 1 std or 1 standard error.
Maybe:

“The image phase fraction is 0.640. Assuming perfect segmentation, ImageRep estimates that the true material phase fraction lies within ±0.076 of this value with 95% confidence, i.e. in the interval [0.564, 0.716].” ?

This way we also remove the relative error, which might be confusing.
It’s also shorter this way, currently the sentence is quite long..

Maybe a better version keeps the relative deviation:
"The image phase fraction is 0.640. Assuming perfect segmentation, ImageRep estimates that the true material phase fraction lies within ±0.076 of this value (11.9% deviation) with 95% confidence, i.e. in the interval [0.564, 0.716].”
