BF fails
Having a possible strange issue with BF'ing a WPA.  (v1.36)
Dictionary attack and rules based got it.  Password is 9 characters all lowercase
But not BF.
What am I doing wrong?

./oclHashcat64.bin -m 2500  -a 3  -t 10 --outfile=./x.txt  ./mywifi.hccap ?a?a?a?a?a?a?a?a?a

This had a runtime of about 1 hour 15 minutes.

This had a run time of 1 hour 7 minutes.

Isn't the '?a'  all characters, numbers and symbols, and '?l'  just lowercase?  Why does a vastly larger keyspace have essentially the same run time?
It's the same keyspace for both attacks. Do you understand what "-t 10" does?

Hint: Both of your attacks have a keyspace of 10^9.
Ah! Light bulb goes off. thanks
