incremental:ASCII - how to mask?

[Snoopy]

Learning how to crack my sample MS 2010 file with simple 6 characters password (two lowercase letters and 4 digits).

While cracking with john 

Code:

$ john --incremental --format=office-opencl johnofficehash

it takes 46 seconds to crack at speed 119771C/s. John manual says that it is "pre-defined incremental modes are "ASCII" (all 95 printable ASCII characters)" Machine is AWS p3 V100 w/ Openwall AMI.

While cracking with 

Code:

hashcat -m 9500 hashcatofficehash  -a 3 -i ?a?a?a?a?a?a?a

it shows 20% faster speed of 142000 compare to john's, but no result after 10 minutes of cracking. Machine is AWS p3 V100 w/ NVIDIA drivers and CUDA.

Am I missing the hashcat masking techique to emulate the john's one?

can you show the output of hashcat when running this cli? anyway, it should be no problem when sorting the options like this but you should stick to the expected form

hashcat options hash maks, so hashcat -m 9500 -a 3 -i hashcatofficehash ?a?a?a?a?a?a?a
