Yes, the math is based on .500 so any numbers other than .500 totals your package. the numbers each side of .500 are added together.
A time slip with .490 red reaction and .010 over dial is a package of .020
A time slip with a .510 reaction and .010 over is a package of .020

Some years before his death Steve stayed three days at my shop and slept in my motorhome. During those three days, we talked constantly about drag racing and his thoughts and ideas. He was an interesting guy, sharp, and a good racer. He even did a powerglide build under my supervision
Steve was friends with the Accutime guy and was making a tour of the South, stopping at several tracks along the way.
Steve and I connected because his Drag 2000 idea was printed in the Texas Raceway at Kennedale race newspaper.
