Section 4.2.3.4 says:

(3) or if at least a fraction Fs of the maximum window
    can be sent, i.e., if:
        [SND.NXT = SND.UNA and]

                min(D.U) >= Fs * Max(SND.WND);

It should say:

(3) or if at least a fraction Fs of the maximum window
    can be sent, i.e., if:
        [SND.NXT = SND.UNA and]

                min(D,U) >= Fs * Max(SND.WND);

Notes:

correct min(D.U) to min(D,U)
