The best way to tell how effective your AM is to scroll your mouse over "Hits" on melee, it will tell you how many blocked vs. hits you have taken. Again, it's not about uptime, but timing when actively tanking. I would agree, that your usage while actively tanking is low. The log you presented, for the entire raid, you sustained 917 full melee swings and 817 blocked hits. Another metric to check is rage allocation. You had 57 ultimatum procs and used heroic strike 288 times. Also, check under "resources tab" and check Rage from the list. A lot of the fights, you're wasting a significant amount of rage, which means you're sitting at a full bar of rage for too long.
Judging by all this, I would assume you're spamming heroic strike
