Increasing dataspan

[haspden]

Could the dataspan be increased beyond 30 days ?
I appreciate that heroku costs would increase as this would increase the load, however you could do 1 to 30 days free as it currently is is and and 30 days plus as a paid service for a small price which would cover the cost ? Just a thought, I love autotune web and run it regularly but a 90day average would be great to rule out the anomalies that an off week can bring in a 30-day period.

Look forward to hearing your thoughts
