The Brain not working as expected (or is it me?)

[Snoopy]

hashcat (v5.1.0-1797-gf9e4dc0d)

Code:

Session..........: hashcat (Brain Session/Attack:0x1cb940de/0xc4361992)
Hash.Target......: .\hash-1.txt
Guess.Base.......: File (.\dict-1.txt)
Guess.Queue......: 1/1 (100.00%)
Recovered........: 1/5 (20.00%) Digests
Progress.........: 10/10 (100.00%)
Rejected.........: 0/10 (0.00%)

Code:

Session..........: hashcat (Brain Session/Attack:0x1cb940de/0x7c78203e)
Hash.Target......: .\hash-1.txt
Guess.Base.......: File (.\dict-2.txt)
Recovered........: 2/5 (40.00%) Digests
Progress.........: 11/11 (100.00%)

Code:

Session..........: hashcat (Brain Session/Attack:0x097e96b4/0x4f82d865)
Hash.Target......: .\hash-2.txt
Guess.Base.......: File (.\dict-3.txt)

looks like it works now like intended

just for me and better understanding, client-feature=2 (sending attack positions) is only applicable to bruteforce/mask-attacks or is it also working on dictionaries? i know hashcat uses "chunks" of work for different opencl devices distributung this work for all available devices
