don't forget the passenger bags. The resulting 1.95m^{3} is only once they're loaded.

There might be a bug in the base value, but given that base value, the remaining space seems correct.

I was excluding forward hold and assuming the bags would go there.

As multiple data points (the Jane's data Sami cites, Tupolev site, Brinkley's Cargo Freighter, ACS) seem to confirm 44.5m3 total lower floor volume, it should be obvious that the available cargo volume is too small by many magnitudes.

I don't know the formula Sami uses to allocate passenger bag space. I do note that the very similar sized Boeing 757-200 (both physically and with respect to passenger capacity) has a lower hold volume of 43.3m3 per wiki and has an in-game cargo volume of 25.3m3.

If the 189/238 max passenger B757-200 with 43.3m3 under floor volume yields 25.3m3 cargo space, the 180/210 max passenger TU-204 with under floor volume of 44.5m3 should have a cargo volume a heck of a lot larger than 1.95m3.

I used the Jane's aft cargo hold figures (15.4m3 to 20.4m3) as a minimum assumption - assuming that the bags go up front and are segregated from the other cargo which would go in the back.
