Many people proclaim, with a good deal of conviction, all kinds of statements and generalisations that just aren't even close to true. I'm guilty of doing this on plenty of occasions myself.
FPV is a topic that seems to bring this out in people. I'm keen to try and collect some real data from people's FPV experiences and produce some sort of decoder that gives people a realistic indicator of what sort of distance you can expect from different frequencies, transmission power and antenna setups, and the relative impacts of atmospheric conditions, topography and terrain. Something that won't be able to be measured is ambient interference, and this may be a large confounding factor. Also, the data collected is going to contain distances well within the max of the system used because people don't fly to the limit all the time.
Let me know if you want to participate and feel free to recruit non-FTers in too. To get any meaningful data I'll need as many data points as possible per setup combination (probably 30-100 per setup to even start to get a trend). I've done up a quick Open Office spreadsheet with a data dictionary on the first sheet and a data reporting sheet on the second tab. I know that not all the units I've got in the spreadsheet are necessarily people's native units. I'd prefer data to be in the units specified, but if you really can't be bothered making my analysis easier, I'll convert them before I stick them in a master sheet.
Also feel free to tell me if I'm getting over-excited/ambitious or if there's someone already doing this. I plan to pool the data into a master sheet and post it with the results in an article on the main site.
EDIT: I've added the spreadsheet to Google Docs, which anyone following the link should be able to edit: https://docs.google.com/spreadsheet/ccc?key=0ApqXMzvBbsbddHdkTGpWWFV6TFBwYmxVWkJpNVB3d1E
NOTE: the 'data dictionary' is on the front sheet, the 'data entry' sheet is the next tab down the bottom of the page.
