[Somewhat off topic, but if you want to try these boosters you need to be able to fly pretty far since they work REALLY well]
My rule of thumb in still air is about 5000' per 10% of battery life. That's around 30mph in GPS mode. ATTI mode goes faster but uses more power. Depending on conditions ATTI mode may or may not net you more distance. I didn't use it on these flights. Just prior to these flights I went out over a mile and measured the wind speed and direction so I knew what I was up against. I then flew directly perpendicular to the wind and it only had a small affect. My speed out was 29-30mph and my speed back was 30-31mph. 30mph for 6 minutes is 3 miles. I can fly about 15 minutes so ballpark I can go 7.5 miles total. Simple math that seems to work with the P3P. I like to have the return speed a little higher than the outgoing speed - just makes sense.
I don't know why you don't see the same numbers. There are many factors. If you are flying into the wind your speed out will reduce and your return speed will increase. I think overall it's best to fly in light wind if attempting long distance. I'm on old firmware 1.1.9 and old Android Pilot 1.0.10. Haven't had a compelling reason to upgrade as this setup is completely solid. I don't think it's any faster or more efficient than later software, it just doesn't ever crash or have video lag.
While I'm doing these flights I am constantly evaluating all the numbers and ready to abort in case of a problem like a big change in wind conditions when the phantom is, or a sudden drop in battery life or anything else suspicious. I've done 450 flights on various Phantoms so am quite used to how they feel while flying.
As for battery life, I baby all of mine: the first 10 flights they only discharge to 50%. I store them at 50%. I have the discharge time set to 2 days but usually don't need it. If I return home with batteries at say 20%, I charge them to 50% until I am about to fly, then charge to 100%. I keep track of each battery and how many times it's been charged. Lately I've been using www.dronehealth.com to analyze the logs and tell me about battery health. It's about a million times better than the DJI app.
Good luck!
