For conclusions you may be right.

However, the question is whether we inevitably need it for decisons.

That's the point. And even more: They are sometimes hardly reproducible.

Perhaps, I should make a difference here between conclusions and
decisions. (Once again, I refer to Nagle's algorithm. The rational
behind his "decision algorithm", i.e. when a packet smaller than MSS may
be sent, is quite interesting here. There is a decision to be made -
without any knowledge about the source or a links possible throughput.
