Help me understand the use case of Claude extra usage. Since they ~halved the value of the $200/month plan, I ran out of my weekly allotment in just a few days. But I had $200 in free "extra usage" credits - for the inconvenience of disabling 3rd party harnesses. Well, it seems to run 50¢ ~ $1 per minute. In a matter of a half a day, that's going to be gone. So... is it meant for people on the $20/month tier that just need 1 extra prompt that day? Certainly anyone on the $200/month plan just has to buy a second account of at least $100/month to get even a day's worth of work done, right?
