You don’t need to be that precise for pedal circuits as you know most components have a tolerance
Caps especially have a fairly large tolerance + or – 20% and greater if a pedal requires matched or close values it’ll usually tell you in the build doc
If you get your components from a good supplier then they should be fine
You should still make sure your values are correct before installing them using your meter we’re all human and even top suppliers can make mistakes with labelling etc
