Where do the announced Increments of the signals to copy come from?

 
Hello everyone,

I'm considering copying some signal. But I can't understand how the announced Increments are calculated for each signal:

For example, I take an account where the numbers are simple:

And we see that, correctly, the increase is calculated in this way:

So far, all ok...

But now let's take a somewhat different signal:

And let's do the same calculation above:

So, if the calculation says 3083.76%. Where does that 4086% announced in the signal come from? It's a 1002% difference!!!

Please, where does this big difference come from? Am I doing the calculations wrong?

There are many more signs where that calculation is also not understood. And unfortunately, it's the first thing you see of a sign.

I will appreciate help, thanks
