I must agree but I think the BASC is a bit more 'hands on' than the BDS.
I was a member for many years but recently had a look at what I was paying for and decided to terminate.
I was quite surprised, but pleasantly I might add, to be asked why I was cancelling my membership which made me think, hmm perhaps they do worry about their membership,
Then I thought ahh, there must be a few of others terminating and now, but only now, are they beginning to wonder why.
As they have followed up with a full blown survey, perhaps my initial thoughts were correct.
