It can, esp if we are talking about something small like tenths of grams. That is why on BST when a yoyo has heavy damage some people list “still smooth” if it is, because it can also affect the play of the yoyo. I would say the play is more affected than the weight, but both can be affected for sure =).
So I know someone with a Kavka Chief that weight 66.4 grams, also an Alec Campbell Chief that weight 66.5. His scale isnt off because the Kavka would still weigh more than the Alec Campbell (supossed to be the light 65.2 gram edition). So I would check the weights on your Chiefs before just so you know.
The only thing I think is they could have made more runs and those later ones were 66 grams, Im not sure? =).
I have a regular Petr Kavka Chief (not the Whale one) I don’t know how much it weighs right now but I will weigh it when I get a chance and let you know.

Thank you Stickman! So I guess that eventhough diff runs are “66 grams, 65.2 grams, or whatever” it actually is different from colorway to colorway, one colorway from the same run might be a tad lighter than another colorway, which is pretty interesting actually so my thread is a good guideline but the bottom line is…
Always weigh your Chief or ask them to weigh if you want a specific weight!
Im still confused that the Kavka Chief that I am eyeing only weight 66.4 grams… I wonder if they all weigh the same or if there are some 66.4 gram ones and some 67.4 gram ones…
Edit:
Ps: Stickman are you sure your Black Bip Bop Chief is 7075? Just wondering because that would make more sence if it was a 6061 black bip bop Chief, I believe 4 were made and sold on Ebay, much rarer than the 7075 BBB Chiefs! =).

Is the regular Kavka Chief any different in colorway than the “Heavy Whale Kavka Chief”? Maybe Im looking at the regular Kavka Chief and not the “Heavy Whale” version? That is all I can think of…
Does anyone know when this Chief was in circulation and Run?
There is no artwork on the side of the box, and there is a sticker on the floor that says this is Solid gold colorway.
It has Onedrop finish(maybe pyramatte), and has laser printing on both sides.
The only place I know that sells this is Spingear.

Do you know the year for each run?
Yes! but I have that all in the documentary script.
Most releases happened between 2011-2012 (1st-10th)
11th released in 2013
12th (I believe) released in 2014
13th in 2016
I have more precise dates in the video script but I don’t wanna plunder that deep rn I just wanted to update the list for general accuracy based off of what I could find
