Assess my mining technical breakdown

Hello all, just did some basic research recently on S9 and S7 mining and wanted to see if I was on the right track in terms of cost/profit breakdown, tech requirements, bitcoin and transaction payout

Mainly, is the BTC per month too high or low per 100 units (and 50 and 25) for both the block mining and the transaction fee? (still confused on how transaction fees work and how many to expect per month). Let me know if this is completely wrong, and if so, what needs to be changed. This does not factor in energy consumption or other costs. Any help or insight would be much appreciated!

Antminer S9 - 100 units

~3K per unit (w/ 1600W power supply = ~$400)

@100 = 340K

11-13 Th/s

.36 BTC per month

100 units → 432 BTC per year @ 4,500 = 1.9M

Transaction Fees: .146 BTC Median Transaction Value = 63 BTC = 283K

Revenue: 2.183M Cumulative

50 units = 972K 25 units = 683K

S7

Antminer S7 - 100 units

~$600 per unit (w/ 1600W power supply = ~$400)

@100 = 100K

4.73 Th/s

.1645 BTC per month per unit

100 units → 164 BTC per year @ 4,500 = 738K

Transaction Fees: .073 BTC Median Transaction Value = 7.3 BTC = 33K

$845K Cumulative

½ = 440K

¼ = 320K
