Offset overclocking

okay, so

voltage set in bios = 1.380
LLC = high
load voltage (according to cpuz) = 1.360 - 1.376
load vid (according to core temp) = 1.2059
**this results in a stable 4.8 overclock on my 3770k

according the offset formula,
it is MANUAL VCORE minus LOAD VID

in this case, it would be:
1.380 - 1.2059 = 0.1741

so this is an positive(+) offset of 0.175 rounded up.

for those who have experience with offset and such, is there any problems using such a high offset number?
most offsets I seen around the web is like 0.050, 0.075 and etc.

***
some might argue, use ULTRA LLC and drop the vcore- the problem with this is, it overshoots the vcore on load way past the vcore I entered in the bios. for example;

vcore set in bios = 1.360
LLC = ultra
load voltage (according to cpuz) = 1.380 - 1.384
load vid (according to core temp) = 1.2059
**this results in an overshoot of volts being pushed into my processor, a whole .020 or .024 over!
anyway, in this scenario...
1.360 - 1.2059 = 0.1541; a positive offset of 0.155

so either way, the offset will be pretty high.
