Alcator C-Mod has been setting records like this for a long time, only with Pressure and Confinement, instead of Temperature and Confinement. IIRC, you need Pressure, Temperature, and Confinement time to be above the critical threshold. (eg. high temperature means nothing if your density is very low, you've barely got any gas)
So it's not clear this actually can be scaled to fusion.
I'll note that MIT's ARC reactor design (SPARC first), seems on track to deliver all three, and in a much more compact body, and with a liquid molten lithium salt blanket design that might actually be workable, and maintainable (e.g. serviced).
However, there's still the problem of helium "ash" and other by products produced by fusion, and how to remove them. It's not a problem now because after 100 seconds, you're emptying the entire chamber, but this means you can only "pulse" the fusion reaction, you can't run a continuous reaction, unless you figure out a way to clean out the products of the reaction, and no one has demonstrated that as yet I'm away. Perhaps the divertor design the Chinese have come up with can do that, but I feel like they would have publicized it as it is a long standing problem.
