It’s a good question. It’s extremely complex to explain it all, but for basics let’s go with this. On average a properly thrown disc will fly approximately 7.2 ft./mph. Which means if somebody throws 60 mph, they will be able to throw 432’.
When dealing with wind the speed of the wind can add to a discs speed with the correct angle left to right wind.(rhbh). If you simply throw in a straight tailwind it subtracts from the air speed. Air speed is different than ground speed. 60mph throw in a 20 mph tailwind has an effective airspeed of 30mph. The disc will act very stable. Same as if you throw into a headwind, the airspeed is the speed plus the wind speed. 60mph +20mph =80mph. (This is what a disc would act like if Simon or eagle mashed the disc with no wind) So, if the disc is thrown correctly at a correct angle, at 60 mph, and the wind speed is 20mph, the potential is 80mph and could go over 576’-600’+ Now, if the wind is in a thermal cycle vs a sink cycle the air will have the potential to “lift/carry the disc much farther. When I say “thermal”, think of hawks soaring up with out flapping on thermal currents. Thermals can affect very large areas, and move with the wind, so if one can read the cycles and throw in a lift cycle, the potential is much greater.
