You are welcome! And yes, that conversion is indeed only as an basis of comparison, the ETS site states that "this is simply because the Bridge is meant to measure lower ability levels than TOEIC does. Hence, the Bridge and TOEIC scores are NOT interchangeable." So, no sense in creating expectations, like thinking that one can go from one to another level, etc.
And yes, I think you have done well if you scored like that, congrats!
