Luffy is telling Kizaru he is 100 times stronger than the last time they meant when Kizaru owned them
How can it be any clear
It takes someone 100 times stronger than Sabaody Supernova to match Kizaru
Which is why Rayleigh did it in his old age
Which is why Luffy can do it
It includes Zoro too as he too was a Supernova hence his strength was also 1/100th of what it is now and 1/100th of Rayleigh
So it directly says Old Rayleigh = Current Luffy = Current Zoro <= Kizaru

However, we both know that Luffy got the most progression among the SHs over that so Luffy is >100x stronger than 2 years ago.
Meaning, that Luffy > old Rayleigh if you use this shit to compare them.
It's basic maths.
