That indicates that the secondary winding is in the ballpark for the correct number of turns for that toroid. Only the primary winding needed to be adjusted to get VFB to start working correctly. The correct place to measure the DC voltage, "UNDER LOAD", is across the DC terminals right at the Power Board terminals or solder connections (carefully!!!). I agree with phil99, looks fine for now, keep an eye on the AC regulation under a few high loads, just to be sure you know what the limits are with the current setup.
