It's not necessarily the size of the gold, more so the density of it. For example you could take a 1 inch piece of the slotted end of a hose clamp and test it with your 5000 and one of your VLF's. I'm pretty sure the VLF's will here it deeper than the 5000. Thinking back on this when I saw this tested they were using a 4000 so maybe the 5000 may not hold true.
