I use about 2 seconds down and 2 seconds up doing bores with a Flex Hone. This is usually with a 240 grit hone (blue blob on the tip). It would be a smidge quicker on each pass with a 180 grit hone (red blob on the hone's tip) I've never bothered to try and get a diamond pattern, just a uniform finish. Any light lubricant should work OK - I use ISO 32 hydraulic oil because I have gallons of it here.
