RMS Power?

I often see power specifications like "100W RMS".  There is no such thing as RMS power.  Of course, you can calculate RMS value from any curve, including power curve, but it won't represent anything.  "Real" power representing heat dissipated in resistive load is "Average Power"   Pavg=Vrms*Irms.   In case of sinewaves Pavg=0.707Vpeak * 0.707Ipeak = 0.5Ppeak,  or Ppeak = 2Pavg. 

Term "RMS Power" or "watts RMS" is a mistake, very common in audio.

When it comes to watts, there never seems to be enough to satisfy some, regardless of how it's measured.
Ultimately, if you can't stay in the same space with it, it ought to be enough.  Unless you're hooked on the smell of things starting to fry.  Then I'd suggest you might need a therapist instead of more wattage.

Just teasing,  but MHO...;)
