DQ hasn't gone off topic. He posted a comment on empirical evidence versus electrical theory - entirely on topic with the preceding posts.
You posted a comment that was defensive about Nick and unrelated to the preceding posts.
DQ replied that "Your desire to provide retorts to my posts, alas means you ignore what i posted and talk little sense".
The above comment from DQ seems correct, to me, based on what you posted and have subsequently posted.
Time to stop playing games. If you are keen to debate with DQ then do so on the genuine content of the thread.
