Can you put up the build & you recharge?
We need to get brawl out of that chain ASAP!! 
I shouldn't try math at 5 in the morning. I'm not particularly good at it at the best of times.
I figured out where I went wrong (on the bus to work a few hours later after my brain had finished cold booting). That 1.4 was completely out of left field, but that didn't matter much because I was attempting to apply it to the enhanced power numbers rather than the base.
Using the base numbers (roughly half) and multiplying by 2.4 (240% for 99% enhancement and 140% fury) gives me 138 which is about what I expected unless I'm still doing something wrong.
Here's the chunk for the slotting numbers (if it works) to see if someone can come up with a better chain with what I've got, but the power selections are final (as much as I wished concept let me dump the god damned useless self rez for taunt).
edit: And the alpha boost I'm using is tier 3 spiritual - Partial radial revamp

Weight training: Because you'll never hear someone lament "If only I were weaker, I could have saved them."
For your posted build, the highest dps single-target attack chain is seismic smash > heavy mallet > stone mallet > hurl boulder > gloom > stone mallet when hasten is down and your +recharge proc is not triggered. At 70% fury, the dps is 155.65 (147.88 if you take into account missing 5% of the time), and the eps is 3.51. The total cycle time for the chain is 11.22 seconds.
The best SM attack chain AFAIK is Seismic Smash/Stone Fist/Gloom/Stone Fist/Heavy Mallet. You might want to build around that.

Gaining 20 dps from pushing gloom down the chain and throwing in throw boulder? Definitely nothing I would have suspected. Nice and smashy though... as long as the boulder doesn't blast them halfway across the room (then it's SUPER smashy, but not as effective). Then again anything I'd want to use said chain on would be immune to said knockback - everything else is dead a few seconds later anyways.
I'll give it a shot. 
How about a chain for when hasten is running? Hasten's not perma, but it's only down for 20 seconds... two chains every two minutes.

My current favorite chain for my stone/wp brute is Seismic Smash, Gloom, Heavy Mallet, Stone Mallet, Brawl - repeat. I know it's not ideal but it's seemless and visually gratifying (I hate stone fist).
I've calculated it at 161 dps (767.99 damage divided by 6.67 activation time for 115.14 dps x 1.4 to represent 140% bonus from 70% fury) but that seems... high?
