Field notes

The setup separates pipe-run calculations from height-of-instrument inputs: benchmark elevation and rod reading feed a displayed HI formula. Material choices include listed wall thicknesses and standard pipe lengths, while users can also enter custom dimensions. The grade-sheet controls offer engineering tenths or inch fractions and an optional halfway station check; the page indicates a ten-run free allowance before a locked-run flow.
