Thank you! I am really interested in knowing how they were disproven, I mean I understand why they would consider unreliable any 380-400 lg tiger but why as example some 280 or some 300 kg ones? If the largest bengal weighed 322 empty after eating a Buffalo how can't amurs reach 280 - 300 kgs... There are some captive HEALTHY males weighing 276-282 kg with one being 4'4 feet tall so if exemplars of this size exist in captivity I'm totally sure they could exist in the wild when there was much more prey to catch

Really? Is the 176 kg average for Amur tigers just the result from weighing unhealthy males? That's great news I am extra tored of hearing that as the average weight of the Amurs.
The average now is 196-203 kg I guess?

They tried to go into detail of the records, and for majority of them it was found that the data came from secondary sources. Many mentions were very vague like for eg,. one said, "There were reports of tigers up to 384 kg" & that was all. Such vague statements and data coming from secondary sources and not first hand made their reliability questionable. 

For all animals, I prefer to consider only the published figures from zoologists for the max size which comes out to be over 272 kg for bengals (272 kg+) from Terai Arc Landscape. Two tigers exceeded a scale of 272 kg which were captured and weighed during the Tiger Ecology Program in Chitwan NP (70s and 80s) There have been verified reports of Bengals at 320 kg like from Nepal (Smythies 1942) but a hunting record is a hunting record and can always be questioned at some time. There was also a male Bengal tiger which was said to have been weighed and verified by Dr. Wasif from Pilibhit NP at 345 kg through pers. comm. and only 2-3 years back but we haven't seen the figure being published anywhere hence it can't be used as a fact, that is for now. 

As published in Slaght et al. 2005, it was 254 kg for amur tigers and 212 kg from post '70 records. However, I believe that the modern records that exist for Amur tigers make us greatly underestimate these cats and older reliable records are a better reflection of their actual size.

You can see the appendix in table one that 3 tigers were severely malnourished and dropped the average. Also, there were 10 tigers that were measured other than STP. Guate included them.
