We had an API call limit of 500,000 for the last two years due to a Salesforce mistake.  They reduced it to 31,000 which we should have and cut off all integrations in production today because we hit that in last 24 hours.  I need to know what our daily API call averages are for longer then just the last 7 days so I know how much I need to increase our limits to and pay for it.  Something that is not in budget or on anyone's radar so I need to get the number correct and not increase it too high?  Any way to get more then 7 days history?
