When was the last time you recallibrated something?
When I get out of a train station and open Google Maps, it usually doesn’t know which way is fucking which so you have to do that figure of 8 thing to get it back on board. Even then though I’m still not convinced. End up walking 50m in any direction just to see where my position has changed to relatively.
figured out it’s easier to measure stuff out a jar by putting the whole jar on the scales and measuring how much i take out rather than put the bowl onto the scales and measure how much i’m putting in
for some stuff anyway (like peanut butter) loads of it always sticks to the spoon and then i eat it off the spoon but i know how much it is because it tells me how much came out the jar
