It seems I have been writing about this subject a very long time. No not specmanship, but the difficulty in coming up with meaningful power duty cycle specs for use in live sound reinforcement.
Back last century, because consumers rewarded them for it, amp makers stopped designing continuous duty (24x7) amplifiers and sold amps that made significantly more power for significantly less time. While extremely short term burst power could be abused, the market place would sort out what amps are wimps soon enough.
Marketing copy is rarely written by engineers and in this case it probably wouldn't help because AFAIK there is no concise spec that is meaningful across multiple genres and applications, and many have tried. Back in the 70's the hifi industry proposed a dynamic headroom spec and that kind of worked where everybody was running amps full range into modest (one box per channel) loads, playing pre-recorded music. In live sound the loading is all over the place and playback bandwidths too.
I wouldn't lose too much sleep, or read too much into these latest adventures in copywriting.
