Mines just a bit worse by that measure(37/35/9/4/1), and on the clickplay measure was about 20% tier 1, 20% tier 2, about 15% tier 3, and about 8% each tiers 4 and 5.

I feel like click play is a better measure for average users you're trying to convert since it's "how well does it work if I just try to start it" as opposed to "how well can it be made to work if I tinker with it enough".

Yours is even better than mine. 87% of my library is Silver or above.
