Tell us about your tachometer. Is this a mechanical thing, electrical, or a handheld LED unit reading a reflective strip?

What numbers would you think not to be 'suspect'? What should be the higher range in forward? 3k is best I remember from October. May have been less. I've limited experience with the A4.
The precise tach numbers wouldn't be the issue, anyway, at all, would they? The loss of RPMs is the issue. I would think this tachometer, accurate and precise or not, would be helpful to indicate a reference point as to whether the issue is worse or better as I attempt to find the solution. Any helpful advice to help solve the issue at hand is appreciated.
At this point, cylinder #1's lack of compression which I've just discovered, would point to a possible cause for RPMs to drop in forward, from all I've seen. Care to add? Thanks.
