In that case I disagree with the prevailing wisdom. If you want to keep your IR current under 61.57 by flying six actual IMC approaches in six months, you need to descend to DH or the MAP/MDA in actual conditions. I doubt most people do that in normal flying, it must be even more difficult if you are UK based because it will have to be on a published approach to count under the FARs. Most FAA people remain instrument current by flying with a safety pilot under the hood on practice approaches (or they should do legally, I know plenty of people who don't)
