Hey there! I started the thread about eating enough so maybe I can help out a bit. Calculating your BMR is a good tool because it lets you know the amount of calories your body needs AT REST just to stay alive and healthy.
First of all, you are doing a pretty good amount of exercise per week. You're doing an hour of cardio on almost every day, plus the weight lifting. So you would probably fall under #4, the very active category. I wouldn't worry TOO much about exactly where you fall into. The Harris formula that you mentioned is definitely a rough estimate based on a certain amount of physical activity per week. I have found that once you figure out the amount of calories that you need to MAINTAIN your current weight (as you did), if you reduce that amount by about 1000 calories you will see the amount that is needed to lose around 2 pounds a week. Furthermore, that amount is usually somewhat close to what your BMR is.
Using too many calculators can be confusing... so that's why I like being aware of my BMR. If a person goes BELOW their BMR, their body is simply not getting enough calories to function in the right way. That was the main point of my thread (that if you keep your calories to AT LEAST what your BMR is, you will stay healthy and likely be able to drop weight each week).
Your BMR is 1,573, correct? That means that if you didn't lift a finger all day, this is the amount of calories your body still requires to function. However, you are very active person so your calorie deficit is much larger than a person who never lifts a finger! BECAUSE you are so active, you should consume more calories than your BMR. I think that 1,650 - 1,700 calories would be a good amount for you to shoot for. In a nutshell, it would be very bad for any (average) person to exercise almost every day yet only consume maybe 1,200 calories... so avoid that.
