Yes, OliThink sets mate.
It doesn't mate how long it lasts, when it's done properly.

Hello Mr. Brausch,
I was just wondering about the long mate distance.
I have never seen anything like it. What is so
different about the engine than the other engines?

Of course, there are some serious bugs in OliThink.
I wish I could find the time to eliminate them, I am happy and grateful for any support
