The "survivability" ratings are very simple. Zero is very bad, 6 is as good as it gets and it influences how well a vehicle deals with a penetrating hit. The spin off to that is crew survival. A vehicle with a low survivability has a low chance of getting out unscathed and one with 6 has a much better chance but all that is influanced by random number variables so there is no gurantee than becasue your tank has 6 survivability the crew will all get out safe and sound...conversley just becasue your vehicle has 1 survivability does not mean that you can't " get lucky" and they all bail out OK but yoiu would be hard pressed to see much of a difference between say........ a 4 and a 5 by running a "kill test" on 100 targets becasue how they are killed is also affected by what is killing them and how much over penetration there is

So I guess the answer to your question is there is no set formula for determining survivability. If something was survivability 4 and it got a decent upgrade I'd give it a 5. If tank XZT is the basic model in 1963 and had a 3 and it was sold and upgraded I might give it a 4
