Of course, because either way, you were out of focus.
A *single* turn of those screws (around the right focus, not when totally out of focus) already makes a visible difference.
With an appropriate high resolution chart, even half turn is visible.
The process of tuning the height of Bettescanning holders is long and annoying: you must take a very sharp original (I use an appropriate FSR-1T chart; a USAF chart would do as well), procede 1 turn at a time scanning at 3200ppi, open in Photoshop, unsharp mask, see if it's better.
When peak sharpness is reached, try 1/2 turns around that point to further enhance it.
It makes a big difference, of course if you have decently sharp originals.
The V700 when used with finely tuned Betterscanning holders can offer good 8x enlargement, see my examples:
