incremental:ASCII - how to mask?

[pipss]

you can try adding options

Code:

-O -w3

for optimzed kernel and workload
and maybe even try

Code:

-S

for slow candidates

My password is like aa1111 so to make it very easy for hashcat I tried w/  mask -1 ?l?d ?1?1?1?1?1?1 Hashcat showed estimated time 4 hours. 

Tried adding flags -O -w3 or -S but it didn't make any difference in estimated time.
