I track my maintenance and reduce by 20%, but that requires tracking.
Is there some reason why you're focussing on 6 meals a day - or do you find this more comfortable than eating say 4-5 somewhat larger meals? Either will work, as long as you're comfortable.
Your calories appear rather low. I cut (slowly, but I cut) on 1850-1900, and I'm a middle-aged woman on HRT who weighs a buck forty soaking wet. Maybe creep the cals up a bit - or at least do a refeed once a week.
Personally, I like my protein high - comfortable for me is about 220g per day and you have a LOT more LBM than my measly 114 or so lbs of it. I don't know what your bodyfat is, but assuming at least 80% of your weight is lean mass you've got at least 150 lbs. How about bumping the protein up to 240g - so about 40g per meal? Keep fats no lower than 75g for the day (at least 10g from fish oil), getting about 25g from each of poly, mono and saturates. Feel free to bump the monos higher than this, for satiety.
If you're hell-bent on the "six meals" thing, how about this:
Training days:
"4 not near workout-window" meals: 40g protein, 14g fat, 12g carb; 334 calories.
2 pre/post workout meals: 40g protein, 7g fat, 56g carb; 447 calories.
Whole day: 240g protein, 70g fat, 160g carb; 2230 calories.
Rest/cardio-only days:
All 6 meals: 40g protein, 14g fat, 12g carb; 334 calories.
Whole day: 240g protein, 84g fat, 72g carb; 2004 calories.
