Yes, the rim is shrinking ---- slightly, which is why spokes are losing tension, especially the slacker left side ones which were barely stretched in the first place. It's just that you made a quick flawed calculation, that coincidentally gave you an answer close to what you wanted. In essence you went once around the monopoly board without bothering to pass Go.
Read Post 2 and you'll see that there is agreement on the effect, --- inflate tires ---> spokes lose some tension. The disagreement is in the amount and what factors are in play.
