Notes: * = calculated based on mbsf-mcd relationship for splice shown in Figure F11. † = within the splice, the following equations apply: cmcd = mcd/growth factor; mcd = mbsf + cumulative depth offset, mcd = cmcd x growth factor, mbsf = cmcd x growth factor - cumulative offset. The growth factor in XCB cores is extrapolated from the APC section. This table is also available in ASCII.
