Thanks that was really helpful

How did you calculate the percentage?

[@AffaAu]

There is a typo in the 1st calculation. The percentage error should be 0.05/1.2 = ~4.17%
The other two are correct.

[@gamingdude7959]

Think of the error as x axis where the origin is the target (100% accuracy) and so the error = difference in x/origin
For example : 0.65 : 0.645-0.655.
Difference is 0.005 so 0.005/0.65 multiplied by 100 is error
