The person said there has not been an update on the blower, but from what she sees the 756 cfm and 234 mph are accurate. She said it is most likely due to new tests showing different averages, or there was a misprint in the past. I highly doubt there was a misprint that they let go for as long as they have, so it must be new testing. With that being said, maybe that is why a lot of people say the 770 blows better then the br 600 magnum. With a difference 33 mph and the little difference in cfm, there should definately be a slightly noticable difference.
The person may have no idea what she's talking about, but it makes sense.
You are still overthinking this....you are just buying a blower. Go to the dealer and have him crank it up and walk around his parking lot and see if it blows. We got 770 and 630 and 620 and 608 and 420 and guess what they all do a fine job. And the 770 is a 2 cycle
and that is why it will be better long term than the 4 mix
