Anyone who has done path analysis knows that
6dB doubles the range. Check into it - you might learn.

I've checked, thanks.

The field strength values I posted are based on empirical data used by the
FCC to determine coverage range, and protection ratios for FM & TV broadcast
stations. The same physics applies to "hams" as to broadcasters.

The free-space path loss formula over a reflection-free path gives different
results. But, as the original post asks " Is it worth it? Will I notice?,"
the real-world values from the FCC curves will give more applicable answers.

Verify my numbers and conclusions for yourself at

You might learn g.
