My last correct prediction of a spike was back on 11/19/12. Nothing in my methods or formulas have changed, but something is different. I’ve checked into taxes and fees, but I don’t see any new ones for Indiana, Michigan, or Ohio.

That said, I have to do something to get back to being correct on predictions. So I went back, fiddled with the numbers, and came up with this. I will start adding 10¢ to Indy/Indiana, and 15¢ to Michigan. With this addition, I would have predicted correctly all but one Spike in both states since 11/19/12. I did not change Ohio because the prediction for today’s spike there was correct, and the two previous spikes there were very close to being predicted, so an adjustment would not be wise until I see where they go.

That said, here’s what today’s numbers would be with the additional “prediction fee”:

Could a spike be in our future? We already had one this week, on an odd day, too since Tuesday and Thursday are the typical spike days. Two in one week are pretty rare, too. But as the market soars, so too will our prices rise. Be on the lookout for a spike in the next couple days unless the market takes a dive.
