OK, fine whatever but the point is that Sidious states to Luke that he can perfectly control the Force Storms, however we now know that he was lying (his boasts were false).
Save for instances when immensely powerful third parties take that control away from him, yes, he does have perfect control.
In other words, he can't, and he knows it, and he decided to lie to Luke so as to seem more powerful.
In other words, he can and only in instances when he is confronted by people with Force connections that are vastly superior to his own, and with the proper knowledge is control taken from him.
Now picture the scene. When he states (and lies) to Luke that he doesn't have perfect control over the Force Storms, do you think he would have even thought of an instance such as being cut off from the force.
That's clearly the only thing that ever happened to make him lose control of a Force Storm, unless you can name another instance in which he loses it?
That's extremely unlikely, and even if he had, it would actually not be lying (it doesn't fall under that catagory) and would be more holding back certain truths, which isn't lying.
He lied to Luke in the first place. If there's something that can take away his control, then he doesn't have absolute control over it. So, yes, he would still be lying.
So I'm sorry escape, but you are wrong, and faulty logical deduction isn't going to save you.
No, I'm sorry, you are wrong, and until such a time when you can prove that Sidious lost control of a Force Storm without a third party interfering, nothing can save you. 😉
