Ron said that his personal standard was to log it if he is in IMC at any point on the final approach course. I certainly was. Additionally, on an ILS, I know the FAF is whenever you intercept the glideslope. Like I say above, I intercepted the glideslope in IMC (breaking out shortly thereafter), so I was also beyond the FAF. But just for fun, take a look at the approach, and read my description:

Here is what happened: I was cleared for the approach and vectored onto the FAC inside the FAF (CLADD) at an altitude of 3,100 feet. I intercepted the glideslope before CEDER, and followed it on down. I broke out at about 2,600 feet, before reaching COGAN (which would be the FAF for the LOC approach).
Bottom line: I guess I will log it, but it wasn't as challenging as a flight down to mins. I don't *need* the approach for currency, but it would be good to have a record of it if I may log it. I log at least five or six approaches per month--sometimes in IMC, but mostly under the hood, mostly partial panel, too.
