Per 2002 NEC 358.26 : No more than 360 deg of bends between pull points.

Yes, if the offset's do not equal more than 90 degrees.

Would you consider 2 regular box offsets more than 1 quarter bend?(90 degress)?

No.

They are typically 10 degrees each for a total of 20. Hence, 90+90+90+20+20=310 total degrees.

i've thrown plenty of pvc in dithes that will assume the natural bend of the ditch.

is this 'bent'?

"is this 'bent'?"
Only if the AHJ can see it!

I once had a AHJ do a rough-in inspection. He counted every box offset as a 90° bend. He was the Senior Inspector for the State on Nebraska. He wouldn't listen to reason and it wasn't worth the trouble to go over his head.

Ever since that time I no longer use box offsets on conduit that will get covered with sheetrock.

When ever I offset EMT I use 30º bends because it's easy to do the math when the multiplier is 2. That would make my offsets 60º so one of them and 3 90º would still be okay. Your offset would have to use 2 bends greater than 45º to make it a violation and that would be a funky looking offset!

To me the bends in the ditch is more than just being about passing inspection. To me its a bend because its gonna cause that much more resistance come wire pulling time.

You know it's a tough day when an AHJ counts box offsets, and considers "the bend of the ditch" part of the 360 degrees. So I think I would ask him, "If I'm bent over 90 degrees at the waist, does that count also?"
