Help from Mods, please: re TDEE & Fitbit

I have also posted about this in the forums, but thought you guys might have a better insight:
After reading your information re TDEE vs BMR and calorie intakes, I'm adjusting my calorie requirements on MFP to a higher level manually (I currently have MFP set to lose 0.5kg a week which gives me 1450 calories per day for). However, I just need a little clarification from people who have a little more experience in this, please. (And yes, I've tried to find info on this in the forums, but am having trouble.)
I used http://scoobysworkshop.com/calorie-calculator/ with the following stats: 34yo female, 64.5kg (141.9lb), 170cm (66.9 inches) tall, 3-5hours per week of moderate exercise.
It came up with BMR 1420, TDEE 2201, Daily calories 1761 (at 20% calorie deficit to lose fat).
I use a Fitbit Flex, and having looked at what my Fitbit estimates as my TDEE to be (2010 based on my history of movement), if I take off the 20% my daily calories should be 1608.
Do you think I should go by the calories I've calculated off my Fitbit TDEE rather than the Scooby's Calculator one?
I know it's only 150 calories a day, but still...that's 1050 calories extra over a week. I just want to make sure I'm doing this right.
Any and all help is appreciated, thanks.

The first thing I would consider would be whether or not you already have accurate tracking data in MFP along with results (change in weight) to pair up with that data.
If you DO have that, then I would use that as your primary means to determine what to do with your intake.
Hypothetical scenario:
Suppose your goal is to lose 1lb/week.
Online calculator tells you to eat 2000 calories.
For the past 6 weeks you've been eating 1620 calories and losing .25lbs/week.
Increasing your calories to 2000 will not likely give you favorable results even though your calculator told you this is the appropriate intake to use.
That's all I'm getting at really, and I know it doesn't answer your question directly since I'm really just returning a question back at you.
If you DON'T have accurate logging data I would either split the difference or start at the higher one and monitor change in bodyweight over 2-4 weeks and adjust according to results.0 -
Thank you for your feedback. Recently (approx. the last 2 months) I haven't been eating well (well over the 1450 recommended by MFP - more like 2000 to 2200 a day - but sticking to my macros), but have maintained using the data from my fitbit. Prior to my lapse in diet, I was losing consistently following the recommendations from MFP and fitbit adjustments.
As I really haven't got sufficient accurate tracking data, I have decided to bite the bullet and go with the higher recommendation. I will sit at this for a couple of weeks and see how it fares, and adjust accordingly. I'll update you with my progress.
Thanks again.0
