Successful Cut?

A question for those of you who do bulk/cut phases. I'm currently trying to slowly cut to about 12% body fat by the end of the summer. I'm trying to minimize my lean muscle loss during my cut so in addition to eating at a slight caloric deficit and doing cardio (which I enjoy), I'm also doing resistance training. Over a span of 16 weeks and per two Bod Pod analyses, 70% of my weight loss was from fat and 30% was LBM. Is this a decent ratio? I was hoping to retain a little more LBM during this cut but perhaps a 70/30 ratio of BF/LBM loss should be expected?

If it helps to answer this question, I'm now at 14.9% BF at 179.6 lbs . Over the last 16 weeks, I lost 6.4 lbs, of which 4.5 was fat and 1.9 lbs was LBM. I'm also 49 yrs old which may factor into my rate of success.
