Can I see a contact's all-time open rate, not just the last 30 days?

It seems the "insight" open email rate (for a specific contact) only pertains to the last 30 days. Is there a way to get an "all time" or "lifetime" email open rate? Is there any way to change the timeframe?

I feel like a rate for the last 30 days does not give enough information? Thanks in advance.
