I used Nuckol's recommendation.
"Body fat percentage ÷ 20 = percentage of your current bodyweight you should aim to lose per week.
So, for example, if you’re currently at 20% body fat, you should aim to lose about 1% of your bodyweight per week. If you’re 10%, you should only aim to lose about 0.5% of your body weight per week."

I'm ~190 and I guess 17.5%bf. Using that I come out to 1.66lbs loss per week at the start. I guess it wouldn't hurt to start conservative. True if this is a 1k deficit that's too much. Hmm
