First off, he never said anything about 'weak'. He said that Qui-Gon is far behind Windu as of RotS. That is a fact. Windu gains insight into his fighting style of Haruun Kal (in Shatterpoint) and becomes more deadly. He gets experience in the Clone Wars, and becomes more deadly. He sees the effects of the war on other Jedi, and becomes more deadly. The experience he gets after Jinn's death elevates him far above Qui-Gon's level.
Windu = TPM Qui-Gon Jinn.
Windu + Time > TPM Qui-Gon Jinn.
