Using hyena butter and 4 full meat pies (20 full bars of energy) I got 102 JB total which is an average of 5.1 JB per full bar of energy.

The range for explores between event encounters was 1-83 with an average of 13.8 explores before an event encounter appeared.

In a single day, you can get 9 full bars, and 60% energy if you use all of it you'll get 48.96 or round up to 49 JB a day.

30 days in September means you can get 1470 JB in a month or 9 GMO cows.

If you have roast lamb or Red Bull and use one a day that will give you 6 full bars and 40% that's 32.64 JB round up to 33 JB.

I wish you better luck than I am having this year, it's not looking good for me.
