I dont follow the logic of your comment.... 
- PHG is power, height and gain.
- most hams should know their power and 
- their height and their approximate gain 

How does transmitting it "guarantee" bad data?
The relative area covered by a station with an
HT and a whip at 10 feet can be as much as
1000 times less area than a 50W station at 300'.
Without PHG data, the two look indistinguishible
in APRS and that is a travesty to the fundamentals
of having a "situational awareness"  radio system.

Further, if he has made a 3 dB or so error, unless
he shows his PHG circle and compares it with his
expectations or experience, then how is he going
to know he is off?
