Set initial gas level

To set the initial gas level you need to manually edit the input.txt file and set the value in the file to 100 + your daily average usage, i.e. if your daily average usage is 1.2% you would update input.txt with the value of 101.2.

How to calculate your daily usage

• Calculate the number of days you use your gas for.
• In my case I used my 48kg for a 117 days.
• Devide 48kg by 117 days and I get an average of 0.41kg per day used.

Next you would need to calculate 0.41kg as a percentage.

48kg = 100%
0.41kg = ?
To Solve for "?" we can cross-multiply and divide:
(0.41kg)*100% = (48kg) *?
0.41kg * 100% = 48kg * ?
41 = 48 * ?
Now, divide both sides by 48 to solve for ?
41/48 = ? * (48/48)
0.8541667 = ?
So, 0.41kg is approximately 0.8541667% of 48kg
