A couple of points, bearing in mind that I admire players who want to tier up.......but be careful of what you wish for.
To answer your question, yes 61 average is required and played 40? ranked rounds as a TM.
Now back to my first statement - looking at your stats (and you do not play a lot of ranked rounds) your game is a long way off being at legend status. You will need to improve all stats to even score remotely well with the longer distances at legend tier.
The other thing not in your favour is low level clubs - when you do get there (for this you will need to play a lot more ranked rounds and the higher scores will drop off, so 61 is attainable, but will need investment in your clubs. A complete review is required.
I would recommend you ditch the Max ball you are using, pricey and only attribute is meter speed.
Until then, many players sadly will avoid you as all they will see is a high level lower tier player. although you are not a bagger in my opinion.
