SC 2.2.1 Adjust "at least ten times"

SC 2.2.1 Adjust "at least ten times"
--
Adjust
The user is allowed to adjust the time limit before encountering it over a
wide range that is at least ten times the length of the default setting;
--
I'd like to confirm what "at least ten times" means. The word "times" can
have multiple meanings, 10 opportunities (number of times ) and 10 times
longer.

Which website will pass SC 2.2.1?

Website A:
The site set 10 minutes as the default time limit for the form completion.
The user is allowed to adjust the time limit before encountering it to 100
minutes which is "10 times" of the default time limit.

Website B:
The site set 10 minutes as the default time limit for the form completion
as well. The user is allowed to add 5 seconds to the default time limit at
least "10 times" which means at least 50 seconds in total.


Could anybody clarify which "at least ten times" means in SC 2.2.1 "Adjust"
?

This question was raised by a member of WAIC (Japanese web a1y committee).
We've been understanding it meant "10 times longer". But it can be read as
"10 opportunities" regardless of the length.


Thanks,
Makoto
