Pretty well spot-on, keygrip!
A few minor points though:
1. Examiner authorisation is not recorded on a 'Ratings - Certificate of Revalidation' form.
2. If revalidating by experience, you have to wait until the last 3 months of the Rating validity period before an Examiner may sign the form, no matter when you achieved the 12 hours. Thus if your Rating validity ends on 25 Aug 05 and you achieved your 12 hours in, say, Mar 05, you'd have to wait until 25 May 05 to have your form signed. This is yet another cock-up of the CAA's own creation; they didn't read the JAR-FCL requirement correctly, so amended the ANO incorrectly. They realised this last year, but instead of sorting out their own cock-up, amended LASORS to change the JAR-FCL "shall be signed in the last 12 months" to read "shall be signed in the last 3 months".... They have been told about this error and have been requested to sort out the ANO rather than introduce requirements to abide by their own cock-up.
3. Don't forget the 90-day recency rule for passenger carrying!
4. There are slight differences in the way the LST and LPC are supposed to be conducted, even though the flight profiles are the same. The LST is intended to be rather more formal as it is a 'test', rather than a 'check'.
