what do you actually mean here? "Apart from time in Paris" is better than anything Pics has won.
plus Tim had more slam semis
oh, and 1999 AO I assume for missed chances, that was a fairly epic chance. In 2000, he had a decent half a draw, but had Kafelnikov in the SF and Agassi/Sampras in F iirc.
It's also worth reamphasizing that the courts were much more diverse during Henman's time. You couldn't just coast from the Australian to the French and expect similar bounces. The differences lended themselves to different styles, different dynamics, and greater chances of upsets/losses.
