Hi Josh,

    Here is what I measure (poly, manual)

Cutoff Ctl at 10:   IC7-7 = 4.91      IC8-1=  -7.36V
Cutoff at 0:           IC7-1 = -4.98     IC8-1 = 7.49

   I would suggest making the earlier measurement after the buffer.
Your meter may be loading down the voltage.   Anyway, the important
voltage is the one that's later in the circuit, and here our numbers are
very close.

    It seems your expected values were spot on, within circuit tolerances.
