Can you please keep HVC on there? You have the only chart that shows its comparative profitability.
Yes, but I'd suggest trying a different pool. I split tested 4 different HVC pools and found ZHPool the most profitable while 1GH was among the lowest.

Also regardless of pool used, pull down the latest software from hvc.1gh.com. The newer software versions for both nVidia and AMD GPUs gives much better MH/s rates.
Latest Versions:
cgminer for AMD GPU (version 3.7.3 2014-04-01)
ccminer for NVIDIA GPU (version 0.5 2014-03-27)
Assuming you are throwing more then 15 MH/s at HVC use:
If using 1GH pool make sure to use VIP as your password
If using ZHPool use port 40001
Regardless of pool, just using the latest software and the correct password (1GH) or port (ZHPool) will make a huge difference in profit.
I'm using latest 1GH software and VIP password. I'm using AMD since that allows better (if somewhat conservative) direct comparison with Scrypt. I'll take a look at ZH, thanks for pointing that out.
