Calling all Nerds - load testing

[Rook57]

Hey guys,

Please see the attached graph and spreadsheet.

A few things:

1) can anyone tell me what's going on with the circled areas on the line chart? It's my load work up look for nodes in .2 gr increments

2) Do you think I should go ahead and test 60.5 gr? 60.4 (Spreadsheet Load 4) looked pretty decent.

3) just run with Load #3?

That's what you're looking for. Those are considered "nodes" or flat spots. Load 4 looks good to me and what I would further test.

I thought the flat spots were the nodes. The dips seem like a spike then a drop, like some kind of pressure change issue. I don't know.

It's not bad to see a slight dip in velocities like that. Because then it picks back up until it reaches the next flat spot
