How accurate is AN 9.20 – Velāma Sutta?

I would really like to ask here: how accurate is [AN 9.20 – Velāma Sutta](http://www.accesstoinsight.org/tipitaka/an/an09/an09.020.than.html) ? * Is stuff exaggerated in places ? * If you give all the stuff Velama gave, wouldn't you get at least a little more than a "whiff of a heart of good will" while doing so - more moments of good will than just one ? I'm not sure I remember all I want to ask about this sutta so if you have anything to add that is welcomed.
