I run two of the waveline 10000s and I some what agree that perhaps the flow-rate is exaggerated but I also use to think the power consumption was higher due to how hot the power supplies would get but after measuring the actual power consumption to be right on the money (85W full power) I seem to think the flow rate is likely accurate as well. I'm not sure why the manufacturer would lie about it. However what the pump curve really looks is probably key here, I just drew a typical curve line to give an idea what it probably looks like, doesn't mean it's accurate. Worst case you could draw a linear line, I've never seen a centrifugal pump do worse than linear.
If someone hasn't tested these pumps before my next sump break down I might do a little test to see what these pumps actually put out but until them I'm pretty satisfied with manufacture specs being accurate.
