I recently decided to make a full season projections for the first time. I am willing to put a lot of time into it. I also decided to only do one or two teams. The main thing I want to accomplish is creating equations for future use. Example(players # 1,2,3... correspond to batters # 1,2,3) How many runs should #1 score if #2 has OBP.370 SLG.430 and #3 has OBP.440 SLG.560. And there are a million other equations like that that I want to get an indication of.

I think this is the best way to create accurate projections. I have looked at others projections for several years and wondered if they used such equations. As I have been doing initial research I have come across several indicators already. One oddity that I have no answer for is that the Reds scored 774 runs last year in 5,942 TPA, while the Astros scored 693 runs in 6,139 TPA. It took the Reds a full PA less per run scored. I have my thoughts on this, it is just a huge discrepency.

I was wondering if some of you do this and know of sets of projection indicators?

I just want to see if there are special things that I should look into while I am making my calculations.
