Home now. Here's the results so far... the eccentricity of the planet is varying on a regular pattern on a 400000 year cycle, but it's only varying between 0.63 and 0.58 (initial ecc was 0.60). Planet inclination has increased monotonically from 0 degrees to about 12.8 degrees over time (this is over 6.7 million years).
So it looks like increasing the companion mass makes the planetary inclination rise faster, unless that's down to the shorter timestep?
I'll start this again with the numbers in the paper and see what happens - I think I can afford a 65k timestep here since the planet's at 2.5 AU there. The inclination increase is strange though - the eccentricity isn't doing anything at all really.
