What would be the benefit in being "fraudulent" about IF time?
Some airlines require X number of hours in IMC (IF), some require X number of hours IFR. I suppose the issue just comes around when someone puts the IFR hours into the IMC (IF) box.
Shouldn't really make any difference once you arrive in an airline, but it tends to be a sticking point for GA pilots attempting to get a leg up. I know of GA pilots flying up North on IFR plans but not logging any IF, due to avoiding flying into the CBs, being knocked back from airline jobs.
I wouldn't know what my IFR time was exactly, I had to fill it in once for a job application and just took my best conservative guess based on the types of aircraft I had been flying (they were only after a minimum time anyway so accuracy wasn't a major concern).
