Match’s results seem to be valid. The BS is the way some people have misconstrued or misused the data.
Match did his emitter tests on a rig that has massive amounts of heatsinking, which he discussed here.
But it seems like some people think or are trying to sell others on the idea that XML2 can be driven to 6A in a small-ish host and expect the same results as Match got on his testing rig. That would be BS.
