I would dispute that. The weight differences between the lower weights remains the same as a percentage of body weight, for example there is a 7lb jump between light welter to full welter but only 5 lbs from lightweight to light welter.

With the lower weights the actual lb difference is even less about 2 or 3 lbs for the lowest weights so the percentage as a bodyweight remains the same.

Pacqiao started out at 106 lbs and has climbed 6 divisions, Morales has climbed 5, Barrera 5, Guzman 3 etc.

Marquez climbing one division in his entire career is actually no more impressive than Cotto, Hatton, Judah, Spinks and a host of others in fact I'd say it was a minimum requirement for any smaller fighter to fufill in order to even be considered for the top 10 p4p.
