Ogorkiewicz was known to have participated in numerous military projects including tank developments, and he was personally familiar with Israel Tal, which might explain why he gained access to the Merkava.
There is no data actually on the weight. We only know official weight, which is 63 tons for Merkava 1-2, and 65 tons for Merkava 3-4.
Those are stats shown on the internet.
For example, everywhere I read, the Namer (APC based on Merkava) weighs 60 tons. IRL when I talked to a maintenance crew who were working on a Namer CEV, and said it was nearly 67 tons.
Just look at the Dor Dalet upgrade for example. It included some very thick applique over the turret sides of Merkava 2 and 3, and on the Mark 2 it also included a thick frontal armor applique. Yet official weight remained completely unchanged.
We have to take official data because that is the entire basis of research and is the closest we can get without direct access to the tanks and testing equipment.
I don't know what you are trying to explain; the Namer CEV is heavier than the base NAMER because of the engineering equipment added, and we have some sources for this.http://farm4.static.flickr.com/3480/384 ... 7cc1_b.jpghttps://upload.wikimedia.org/wikipedia/ ... Evenor.jpg
The second picture is that of a Namer CEV without the dozer at 63.5tons, and with the rest of the equipment 67 tons would be plausible.
I don't know about the Dor Dalet upgrade and if you have sources bring them forth and they can be scrutinised and cross-referenced.
Allowing for better morphology of armour and perhaps some kind of composite armour the Merkeva II would slightly better amoured than the I on the hull, but without changing the dimensions on the hull there are severe limitations of up armouring because 1) The engine need room for cooling and there is a lot of surface to cover on the hull.
There are servre limits on the fundamental design and layout of a Merkeva style vehicle that skews the firepower, mobility and armour ratios in favour of crew protection. This is why no one else has done such a MBT.
