It’s a 90′s thing. Bob was acknowledged as the king of array formulas. I came along and learned from him and perhaps became his equal. However, I don’t think that either of us ever reached the level of innovative uses of array formulas that you have. Honestly, I think that Oscar at get-digital-help.com is the current “king” of array formulas. However, DAX formulas are like array formulas on steroids, and represent the future in data analysis.

King?

No doubt you guys rock.

I’m happy with “hero!”

Bob Umlas and I would (in a friendly way) challenge your assertion of who is the king of array formulas.

There is a person that knows array formulas the most and actually is teaching how to use them in your work – check http://academy.excelhero.com/excel-hero-academy-tuition/

So, EPD means Engineering Professional Development, per the author of the workbook. I guess it’s not really a coincidence that it could also mean “Excel Pro Developer” or “Excellent PowerPivot Designer”, both of which apply to Rob and his partners.

We expect to be in “full production” with an expanded version soon.

THANK YOU again to Bill, John, Rob, Jeff, and Nan for your enthusiastic and creative interest – and thank you to everyone who commented on the earlier post!
