About Time To Win

In 1.2.0, we can run chia farm summay to know Expected time to win time.
But, in chia-monitor, calculated time difference is large.

Is it possible to use the official calculation of the chia project directly?

[philippnormann]

Hey @KevinMyDing, that's an impressive farm you got there! 🧑‍🌾
We are currently using the target seconds-per-block constant with a value of 18.75 for the time-to-win calculation. When blocks are created faster or slower than that, the calculation can indeed become slightly inaccurate. I agree that we should use the exact calculation using the actual average block time over last couple of hundred blocks. I'll see what I can do 🤓
