I was flying from East Midlands yesterday and the forecast cloud tops was between 8000 and 10,000 feet, however when i got up to 3000 and I was through the cloud. saying that, there was another layer of cloud above me, base of about 8000ft as an estimate, but as far as i remember this isn't what was forecast (not that i'm complaining, got some more good pics
)
If I remember rightly there is an equation to estimate the cloud base as well as one for cloud tops, I just can't remember what they are. I remember using them in the past and never agreeing with form 215.
Cheers

PS. I was landing at east mids at about 1345 yesterdsy and it wasn't really dark, but they did have the lights on
