Caliper showed washouts; bumped cement top — fewer water hits; still “double-check drift” on densitometers.

“double-check drift” — we keep a 10.0 ppg NaCl standard on location and re-zero/span the densitometer at the blender before each stage; if temp swings >10°F we warm the standard to match line temp, which stopped our density sag late-stage and cut water hits. @c_smith89 you doing anything similar?

Quick example: we hit an unexpected ovality on caliper and throttled rate by 0.5 bpm while running a short 16.4 ppg tail there; the real save was a mid-pad deadweight test on treating-pressure transmitters — found a 180 psi bias that would’ve made “early screen” calls misleading. If time’s tight, at least spot-check the low-pressure line with a handheld gauge; @t_graham76, are temp swings biting your Coriolis more than the densos?
