The signals on the ground are far weaker than the TVFool simulator estimates because it doesn't take into account the vertical elevation pattern of the transmitting antenna(s). At 1.1 miles from Sutro, the main signal lobe is probably more than 1500' above his head at Market and Castro. As a result, the TV signals are likely anywhere from 10 to 40 dB below the forecasted levels. FM radio signals , OTOH, are a different story. and are more likely to cause issues than the TV signals from Sutro.
