I would tend to agree with you, AirOli:
BA Silver = AA PLT (= OW Sapphire)
=> LX TC Silver
BA Gold = AA EXP (= OW Emerald)
=> LX TC Gold
---
BA Premier = AA MM
=> LX Circle
Now, regarding the bonus miles, as pointed out by Guy Betsy:
LX TC Gold 30% bonus miles seems very little when compared to BA EC NA Gold and AA EXP 100% but then again compared to BA EC EU Gold/Silver(CH) with only 25% bonus miles, it's not that bad ...
I guess - once again - it all depends where you are based: Location, location, location!!!
