the thickness of a dime

It's amazing to some but a simple fact to those who spent years on a bike. I've recently had to replace a seatpost on my bike, it's one of those things(along with setting up new shoes) that I dread. The reason MANY of you LOL may be wondering? I can tell if the height or saddle position is off/wrong. Sure I take the necessary steps and measure the existing height etc, but muscle memory in my legs can tell if it's not exact. That in and of itself can drive you crazy. Thats why you see me on the side of the road making adjustments more times than I care to admit when on a new bike. SOOO, yesterday after a couple roadside stops, I felt like I may have dialed the position in. I went home and later pulled out a tape measure that had been marked in years past with a spot that was right on. Low and behold what I adjusted the seat to on the side of the road, was EXACT to the measurement on the tape measure. The adjustment was no more than the thickness of a dime. Merckx would be proud LOL
