I have something similar.

The issue with your file is that the most profitable coins are NOT on what to mine

So it is a good IDEA to add your own algos and calculations. It is quite easy to connect to blockexplorers API to get the hashrate and also add price API from coinmarketcap ( if it is listed) or even better right from the exchange.

Requires much more manual work though

EDIT: I also think your nethhash24h calculation is not entirely correct
