Well its nice to have bot behaviour explained in such detail.
That said, as others have commented, my personal experience seems contrary to these rules.
Most recently in a Tier 10 match on Scorpio, I had just been killed near the end of the battle. I decided to respawn. My tank (an XM1A3) re-appears near the near-side end of the bridge, then without firing a single shot, the game spawns a Superior XM1A3 and a T-15 right in my face. The T-15 tracks me almost instantly, then keeps me perma-tracked so it can ATGM me to death.
A few days ago I was playing the C13 TUA on Cerberus (with the flash-reduction / camo while shooting upgrade). I decide to drive up one of the slopes near the edge of the map, to give myself a good view...and immediately get spotted by every AI driving along the bottom of the valley / whatever, to the point I can barely get a shot off. Would like to add I was also trying to use the few bushes up there for cover too.
Similar happens when I play my PL-01 on practically any map. Most notably Watchdog & Sapphire. Even though I have the Adaptive Camo upgrade (which is apparently equivalent to a layer of foliage) and knock over trees to use as cover wherever possible...I STILL get spotted ridiculously often. Quite frequently when the game just happens to spawn a random bot right near my location, so I'm probably proximity spotted...then every AI knows where I am and seems to target me.
So yeah...my experiences don't seem to match the official rules at all.
EDIT:
----------
And just to add another one to the list: just tried to have a go at Ghost Hunter in my PL-01. Helped deal with the Bradleys that usually show up at the start...then another bloody T-15 materialises out of nowhere, tracks me and ATGMs me to death. This is inside the first minute of the game. At least 3 of my team mates were further forward than me...yet I got targeted!
