If you observe an apparent max zoom of approximately 50, that sounds like a
limitation of JavaScript's number class, which uses
http://en.wikipedia.org/wiki/Double_precision_floating-point_format, which
can only exactly represent numbers up to 2^52.

However, JavaScript also casts numbers to signed 32-bit integers for bit
operations, which would make the effective maximum zoom 30 or 31 where we
use bit operations for speed. So I wouldn't expect zoom greater than 30 to
work.

If you can provide a link to your site we could comment in more detail.
