First of all, one should understand that the time and frequency domains provide different perspectives of the SAME event or Analytic.

Absolutely.
The IR can be manipulated and then displayed in all sorts of ways.
I really don't see how or why ETC devotees repeatedly put forward the notion that it is a superior or the only proper way to view the information. Both types of graph illustrated the floor bounce.
IMHO the frequency response graph showing the comb filtering is the most visually alarming.
However, no matter which view is chosen, it seems to me vital that perspective is applied.
e.g. Vicious looking comb dips are audibly insignificant if they are narrow enough.
When view controls are applied to lean toward the audibly significant, the 'problem'
appears relatively small. Certainly compared to modal issues.
It is just another tool in our kit. In this case it forensically identified the source of the dip. Let's remember that mixary identified this earlier with a tape measure
We have seen in other threads ETC being used to identify a triple bounce reflection. At that time I regarded that bounce as low level and insignificant.
Ditto here.
I will however stick with the carpet :-)
