Hi lobo,

you are correct 81/ 1760 = 1/22 + 1/1760

I feel much better now knowing you at least read this post all the way through! Each of my previous post contained similar intentional errors. My way of telling if you are actually reading the post or just blowing smoke. This is evidently the first of my post you read all the away through, because you didn’t point out my other errors, and I know you wouldn’t pass up a chance to correct a mistake.
