Launched: 3 new metrics in Data Export API

[Nick]

Hi,

We added 3 new metrics dealing with site speed performance to the API:

- ga:pageLoadTime
- ga:avgPageLoadTime

- ga:pageLoadSample

We also updated the values for 2 metrics:

- To specify currency values in filters, you must specify the actual value passed in from the tracking code, (e.g. 1 unit will now be specified as 1).
- ga:CTR now returns the actual percent (e.g. a value of 2% is returned as 2).

Thanks!
