Hi,

Recently I've been comparing my own calculations with WTM and they are always slightly different! I'm trying to figure out whether I made a mistake somewhere in my calculations or WTM Calculator is wrong.

Example from Decred (DCR) Coin page:

My hash rate: 1000000000000 h/s (1 TH/s)
Network difficulty: 19,486,988.241
2^32: 4294967296
Seconds in one day: 86400
Block Reward: 14.3077

My Calculations:

Time to find one block = Difficulty*2^32/My hash rate =  19,486,988.241*4294967296/1000000000000 = 83695.9771926 (seconds)

Blocks per day = 86400/83695977.19 = 1,0323077

Coins per day (Daily Est. Rewards) = 0.001032308*14.3077 = 14.7699486 DCR coins

Using the same inputs WTM Calculator shows Daily Est. Rewards = 14.715472 DCR Coins

I know that the difference is very small, but would like to still figure out who is wrong here.
