New features: peak days and pre-rise baselines

chart-prb-annotatedI’d like to introduce two new features I’ve brought online over the past several days.

Peak days are automatically calculated as the last day of the most fertile sign — either lubrication or egg-white mucus. The calculated peak days appear in the table and also on the chart. Optionally, you can override the automatically calculated peak days in any cycle on the Edit Cycle page. This is handy if the most fertile sign during a cycle is not lubrication or egg-white mucus.

Pre-rise baselines are also automatically calculated for each cycle, using the three-higher-than-six method. Disturbed observations are disregarded in the calculation, so be sure to mark them carefully. Like peak days, you can override the automatically calculated baseline temperature for any cycle on the Edit Cycle page.

Humbled by recent usage

Even though the site isn’t finished, a number of people have recently signed in and created new accounts. In particular, there’s been a noticeable uptick since the beginning of the year. Many have even started charting.

Thanks for the vote of confidence!

Since the site is still not feature complete, I’ve bumped the end date of the free preview period back to March 31, 2010.

The minimal set of features I’m envisioning includes:

  • Plotting baseline temperatures
  • Printable charts (PDF)
  • Optional sharing online with instructors

Until then, please continue to enjoy the free preview!
