calculation of the pipeline()

I am reading through with API Doc, and found in the section of pipeline, there is a chart for VWAP:

I found my calculation is different to the document. the documented result is: AAPL: 5.0, FB:5.5, MSFT:6.5.

While my calculation is:

AAPL: (100*1.5+300*3.0+150*4.5+100*6)/(100+300+150+100) = 3.6
FB: (250*2.0+200*3.5+400*5.0+200*6.5)/(250+200+400+200)=4.3
MSFT: (200*2.5+100*4.0+300*5.5+250*7.0)/(200+100+300+250)=5.0

So do I make the right calculation for VWAP? Or otherwise, how shall I make it to the result by official API Doc?
Best regards, Allan

@allan it looks like the diagram is just wrong. Good catch! I'll update the docs.

@Scott would it not make sense for the diagram in the API to actually be for the example that is being represented in the API. It's just weird to be walking through the example about simple moving averages, and then use VWAP in the illustration.
