Can [aux.verb+have+p.p.] mean the future in the past?

would seat is sufficient, but would have seated is not wrong.

Hi,

·I had estimated that it (.......) less than a hundred.

Which is the appropriate tense (mood),
"would seat" or "would have seated"?
Or both?



I think when the modal verb "would" (is it a modal verb?)

The original constructors: The hall will seat 100 people.
An archeologist: The hall would seat 100 people.
Me: They say the archeologist estimated that the hall (...) 100 people.

Can you say "the hall would have seated" with the same meaning
as "the hall will seat" or "would seat" except the time order?

Your question seems to be the same as the one already answered above. However:

The original constructors: 'The hall will seat 100 people.'
The original constructors said that the hall would seat 100 people.

An archeologist: 'The hall would have seated 100 people.'
Me: 'The archeologist estimated that the hall would have seated 100 people.'
