Gusmeroli did not deserve a medal at the 1999 Worlds. Her jumps were weak, especialy in the long program.
Kwan was also majorly held up in the SP at the 1999 Worlds and deserved 7th or 8th in that phase.
The podium after Butyrskaya probably should have been some combination of Rechnio, Malinina, and Soldatova.
How can a 5.5 be fair when she fell on the double axel, had a shaky lutz combo and did only a triple toe as solo jump? That's mathematically not possible.
I was rewatching Worlds 99 the other day and I found Kwan's skating very lacklustre in that whole competition. Malinina, Rechnio and Gusmeroli (not to mention Butyrskaya of course) were all better than her IMO. Soldatova only in the SP, though.
Malinina likely lost a medal in the short program where I thought she deserved to beat Kwan in that segment.
Others like Rechnio, Liashenko, Poth were undermarked.
Even U.S reporters all agreed at the time Kwan was held up in the short program.
the rules in effect in 1999, the deduction for a fall on a solo jump was exactly 0.4. Not minimum and maximum -- that was the deduction.
Now, of course, the judges were free to set the base mark for the program as a whole wherever they wanted to, up to 6.0. So the maximum score for required elements would be 5.6 if there was a fall on a solo jump and no other mandatory deductions.
Within those parameters, there's room for disagreement.
