You have made the assumption that everyone who uses strong passwords can remember them in their head :-)

10x worse is pretty bad, even though it is only 10 seconds total.
I'm recently switched from a bank that uses regular passwords to a bank that uses partial passwords, and it took me a week or so to get used to this, and it is a little slower (takes me like 10 seconds instead of 1), but it's nothing significant.
