My astroware says max was at 2007 Jun 09 02:45 45° 23' 27" and will be at 2015 Jun 06 18:29 45° 23' 40", about 2.34, and next is 2023 Jun 04 11:00 45° 23' 57", about 2.31, and then 2031 Jun 02 03:33 45° 24' 11", again about 2.31. That's affected by the tilt of Venus's orbit, and the eccentricity of the Earth's, but 2.4 is close to an average value I believe.
