By my own /usage numbers, the €200 Max plan gives less than 1.5x the weekly capacity of the €100 one
I ran a small test with /usage on both Max tiers and the weekly math genuinely surprised me. Putting the numbers here so people can check my reasoning, because if I've got this right the value gap between the two plans is way smaller than the price gap.
On the €200 Max plan (the 20x), running Claude Code: I used 40% of a single 5-hour session and it took 10% of my weekly allowance. So a full 5-hour session is a quarter of the week. The week works out to 4 full 5-hour sessions.
On the €100 plan (the 5x), a full 5-hour session costs about 8% of the weekly. That's my own read and it probably swings between 7.5 and 9%, since /usage doesn't show decimals. Divide it out and the week is worth 12.5 five-hour sessions.
Here's the part that got me. Inside a single 5-hour window the €200 plan gives you 4x the €100 one (makes sense, 20x vs 5x). But stretch it to the week: 4 sessions on the €200 plan, each worth 4x, so 16 "€100-session units" of capacity. The €100 plan hands you 12.5 of those same units. 16 / 12.5 = 1.28. Even if I'm generous with the ranges, best case it reaches something like 1.5.
So a plan that costs double doesn't give you even 1.5x the weekly ceiling of the cheaper one. Everything is sitting right there in /usage. A couple of test sessions and a basic rule of three and you land on the same figure.
This is the bit I keep chewing on. Depending on how you actually work, two €100 accounts can beat one €200. Same spend, higher weekly ceiling. The catch is the burst: one €200 session equals two €100 sessions, so the two-account setup only wins if you rarely need more than half of a €200 session in one sitting. I do cross that line sometimes. Not always, but it happens. So it's a genuine trade-off, not a free lunch.
Real question for the rest of you: am I misreading /usage, or does this match what you see on your own accounts? Would like to know if the weekly ratio holds up for people who push a lot harder or lighter than I do.
