Anything above 500 grams is very good.
There is a bit of variance on the testing. Sometimes it doesn't make sense.
The rated one model at 325 grams, never plugged it.
Then I put in a rated 650 gram model, and plugged that one.
The test uses 3/4" by 4" paste wrapped in plastic now.
When they tested with unwrapped paste, the numbers were lower. Now they slide through quicker.
Some of it depends on "when" they were tested, and the method they were using at the time.
