Using another site to find your TDEE?

Shyloh1

I was just wondering if anyone used another site to figure out your TDEE and used that to go by instead of what MFP has you set for Maintenance?

Here's an example of a site: http://www.webmd.com/diet/healthtool-metabolism-calculator

I may be way off base on this,just thought I'd ask.

Thanks in advance!
