 the whole weekend to grind that last 4 levels to grandmaster
Congratulations.  "In the olden days" I never got a character to GM, and I was level 40+ for months.  Bonanza weekends with their bonus XP rates that are around nowadays are a boon and incentive especially to those who had little to no idea of MUDs and levelling with our first characters. 
If it would have taken you a weekend to get those last few levels anyway, then perhaps the Bonanza bonus only helped you slightly, but it definitely did something.
