As you can see the break even is if you use a minimum of 35% at night, not 75%.

Last autumn I posted the formula for working this out (here).

If my presentation of the formula doesn't make sense, here it is in someone else's post from 2007. I think they've presented it better than I did.

For the Flexible tariff quoted above, the break-even works out as 74.8% day rate.

For Loyal, it's 92.6% day rate.

You missed the statement that you start saving at minimum 75% NIGHT rate.

 if you use 75% at night and 25% during the day it is worth it

If you refer to my 35%, that was in relation to the sample for one EDF region. For that sample the savings only started at 35% night usage. 

I don't think there is a general formula, the point where you start to save differs from supplier to supplier, and as we see with the two Octopus tariffs, even between tariffs.

I am not sure where the difference is when you say break even is at 74.8% day rate and I say it is at slightly over 25% night rate. For me that is the same looking at it from different sides.

I definitely didn't miss that statement. What makes you think I did?

There is definitely a general formula, and I've given two links to two separate posts where it is presented. (In both cases we've omitted the contribution from standing charges; including those would make the calculation somewhat more complicated.)

I don't know what point you're trying to make here? I agree with you but somehow you want to argue over it?

I think you are both in agreement, this bit:

Was a reference to Mstty, not you, incorrectly suggesting that you needed 75% used at night before E7 made sense when it is usually the other way around, as per your numbers.

The two of you are on the same page so nothing to argue about

Yes, no chance of winning if we say the same thing anyway.

I think we agree that everybody will at least use 7.4% electricity during the 7 hours of night rate. So I would see no reason to take a single rate for this offer.

Very handy formula, thanks and changed my (I think) statement
