Wrong cannon tube life?

Crewmen, you want the M199 cannon tube on your M198 towed howitzer howitzer: see artillery.  to last as long as possible. But in some cases, that's not happening.

The problem comes when DS performs a pullover gauge reading. They usually post "Borescope A borescope is an optical device consisting of a rigid or flexible tube with an eyepiece on one end, an objective lens on the other linked together by a relay optical system in between.  Serviceable ser·vice·a·ble

To do that, they're supposed to use Table K-2 in TM 9-1000-202-14, Evaluation of Cannon Tubes. Based on the wear reading, the table provides a new EFC count--usually a pretty big gain. That means the cannon tube's life is extended.

But if the corrected EFC count isn't added to the Remaining Life (EFC RDS) column, you'll probably just continue to use the old EFC count. That means the cannon tube's life goes down faster than it should.
