it's pretty close. not bang on but close enough I'd think it shouldn't cause a problem. it's very similar to the line above it which is fine if you free rev the engine, a little lean.
will post a file when I can work out how to do it again. Been a while
BTW i have ego on low ~800rpm to regulate lambda accurate around idle to try and get some decent emissions readings. That's why it starts messing with fuel while it's cutting but if i want to disable fuel cut it's not having it.
