Excellent points made by all. I appreciate the comments.
I agree that capital ship projects are sort of the exception to all the rules as they can take years.
My shelf Queens have gradually been whittled down from ten to three. Getting seven of ten going again was really difficult. The point about stuff going of the shelve taking years to return to is very true for me. I really really shouldn’t start a new crop of shelf Queens.
Still waiting for from the past
