I was wondering why Tablo support thinks your signals are too strong. This seems to answer the question:

A GOOD tuner should be able to receive signals much stronger than -50 dBm. Apparently, the Tablo tuners don't meet the ATSC specs:

RECEIVER PERFORMANCE GUIDELINES
5.1 Sensitivity
A DTV receiver should achieve a bit error rate in the transport stream of no worse than 3x10E-6 (i.e., the FCC Advisory Committee on Advanced Television Service, ACATS, Threshold of Visibility, TOV) for input RF signal levels directly to the tuner from –83 dBm (-34 dBmV) to –5 dBm (+44 dBmV)for both the VHF and UHF bands.

-50 dBm + 49 = -1 dBmV
Cable guys want you to have at least that much signal at the wall plate for your TV.
Maybe they got the idea from SiliconDust. 100% on the HDHR GUI is only one dB more at 0 dBmV.
Most of my Sony TVs say MAX or 100 at 0 dBmV except for one model that goes much higher:
