Update speedo with tire size necessary?

I have run a few quick numbers on an online calculator and have noticed the very small variation in speedo/tachomoter accuracy going from stock 32's to 33's. It got me wondering, do most people get the Procomp, or whatever recalibration model and update this for such a small change, or do people just say whatever, it's only 2 or 3 mph, not worth $150. I could see where if you run aired down, it's worth it to change the TPMS and you would get the unit anyways, but if you don't every really run aired down (or not often enough to care), well...

Again, I am guessing they are very minor (and livable) differences at this small change. But I could be wrong, as I am only guessing.

By the way, are you stalking me or am I stalking you? Where's the new bumper picks?

You can use this to help determine the differences. Car / SUV / Van / Light Truck Tire Calculations

Both lol

"With the speedometer left uncorrected, there is a major degradation in the performance of the stability control (ESP), transmission shifting, and engine performance"

Copy and paste job ^^^^

Well, if it was set on a stock setting, you'll be putting on less mines on the odometer with larger tires. If you already have it set on larger tires and don't bring it back to the smaller tire, you'll be putting on more miles than you actually drove on your odometer.
