Replace the inaccurate CFM-based formula with nozzle-primary tables
sourced from industry standard abrasive blast cleaning references:
- Pressure pot: midpoints averaged from two reference tables
(#4 nozzle: 115 sqft/hr, #5: 175 sqft/hr, etc.)
- Siphon cabinet: dedicated siphon cabinet reference table
(#4 nozzle: 125 sqft/hr, #3: 75 sqft/hr, etc.)
- SiphonPot: 80% of pressure pot rate (open gravity feed, no enclosure)
- WetBlasting: 60% of pressure pot rate (water-media reduces velocity)
CFM is removed from the rate formula entirely — nozzle size determines
throughput and CFM draw, so CFM is a consequence of nozzle choice, not
an independent variable. Override field still bypasses formula for shops
that have measured their own throughput.
Also corrects TierDefaults nozzle/CFM pairings which were mismatched
(e.g. Small tier had 40 CFM assigned to a #5 nozzle that needs 150 CFM).
