Calculating Efficiency - Grain Points Values

[kfm]

I'm working on calculating efficiency from my AG brews and I see from other posts that there is a value attributed to each grain type, expressed in points. Can anyone kindly point me to a full list of grain types and their points value? Google, for once, has not returned anything definitive. Thanks
