The tolerance is for what ever country that site is from. Its not relevant here. I just ignore that. The formula is good though. I checked it against my manual measurements from compressing the rear end and the result was exactly the same as just entering the data and letting the calculator do it. I normally play around with the measurement to the axle and the actual shock stroke to see what difference it makes in wheel travel. Sometimes just a few more extra mm shaft travel can have a dramatic increase in wheel travel. I normally include ½ to ¾ compression of the bump stop depending on material/design.

That's a cool calculator, LWC. No longer in the dark regarding lengthening a swingarm.
Thank you for posting it up.
