BMR / TDEE questions.... Thanks in advance

Hey everyone I had a few questions..



My TDEE - 3491 (based on active 6-7 times a week... I actually am doing cardio in a.m. for 45-60 mins and weights at later in the a.m. for 1 hour then 30 mins more cardio... so I calculated 1.725)



My BMR is 2024 (6'1 227 lbs 34 yo... )



So here are my questions:



1. I am trying to lose weight.... 227 is retarded... I want to be around 200 lbs. How much under my TDEE should I be eating?



2. Is my TDEE pretty accurate?



3. if I'm doing 1.5 hours of cardio (HR up around 140-150ish the whole time) + 1 hour weight training 5 days a week... does that sound like 1,400 calories? Since that's the difference of my BMR





Thanks for any help!
