Nothing is estimated. Progress is a count of pieces ticked off the cut list, in feet and in pounds — never a judgement about how far along something looks. Facts are stored once and everything else is derived at the moment you look, so there is no status column to fall out of sync. Both completion projections are suppressed entirely below five logged work days rather than fabricating a number from too little data.

Labour follows joints, not footage. Between two spools of equal length, the one with twenty-four welds is the harder one — by roughly six to one, and footage gets that backwards. Each spool is weighted by its footage plus its joints, with an effort per connection type and a weld scaled by diameter. Joint type is read from the cut list’s own material spec rather than typed in, and cycle times come from the estimate’s implied rate for the job — no book rate, and nothing for anyone to enter by hand.
