Industrial style. Book each setup, see the loop close inside its allowance, share the misclosure back, then drag a grade line and read cut, fill and the rod for each peg. Level Loop is a level book for an automatic level and staff. Book each setup, close the loop on a benchmark, and turn the adjusted heights into a grade you can stake. BOOK EACH SETUP Backsight, intermediate sights with a chainage, and foresight, reduced by the height-of-instrument method as you go. Drag a drawn E-pattern staff (or a Philadelphia rod in feet) under a fixed cross-hair, step it by a millimetre, or type the reading. Read the upper and lower stadia hairs and the sight distance is worked out for you. The ΣBS − ΣFS check sits under the book. CLOSE THE LOOP Close on the start benchmark or on another one. The misclosure is set against an allowance of C × √K mm, with C = 4, 8, 12 or your own, and K from the sight distances or the route length. A dial shows how much of the allowance is used and bars show each setup's share. Setups with unbalanced sights are flagged. ADJUST Share the misclosure back by distance or by setups. Turn on the collimation correction from your last two-peg test and see the misclosure change. TWO-PEG TEST Four readings from midway and near peg A give the collimation error in mm per 30 m, with a drawing of both setups and an OK or ADJUST verdict. GRADE AND STAKES The booked ground becomes a profile. Drag the design line, long-press it to add a grade break, set a minimum fall and the width. Cut and fill bars and volumes follow the line, and the stake sheet lists the rod to read at every peg. Benchmarks with descriptions, search and editing. Share the book with its closure, or the stake sheet, as CSV and text. Metres or feet. Industrial style: ruled ledger pages, pressed plates, brass benchmark discs. Everything stays on this iPhone. There is no account and nothing to buy.
