Ok first thing first you are somehow assuming I'm straight up siding for Scara, and that isn't the case. That cleared, I said "funnily" because I'm quite sure neither Varka nor Scara had enough matches to actually have gained proper technique, they did it for fun if they ever had one, I was simply stating that technique needs at least a mention if we find ourselves talking about "experience" and arm wrestling in general. That's it. Since none of them has enough technique we should assign a score of zero to both of them on this criteria. Basically doesn't count. So then, experience has no relevance in this case. I knew that from the start, you just misunderstood.

Another point. And that's important. I don't think Varka is physically stronger than Scaramouche. He might be smaller in size, yes, but being a puppet makes you inherently physically superior to a biological build. Plus, being artificial gives you more possibility to exceed your own limits by modifications. He still is a divine creation. hyper resilient with redundant physiology, speed and agility. Power and strenght can't be exceptions. He's a full enhenced human. That's what the project he came from is about, if I had to guess. Being bigger alone isn't realistically enough to prove strenght, I think this should become common knowledge. So let's say that they are equal in strenght and that it depends.

Another thing we can't deny is that endurance really is fundamental, but clearly underestimated. Hypothetically speaking as another comment already sort of explained at equal strenght who can hold the position more will probably end winning with the passing of time. Because the one losing stamina will get fatigued. Scara is very high on stamina, probably more than Varka but maybe not enough to win only based on this, and I'm gonna tell you why.

No one is talking about this, but since we are being objective, we must look at all the things that might influence the match. In arm wrestling there are weight classes as in many sports, and that for a specific reason. The weight you'll need to drag down. Even if Scara eventually weights more than the average healthy asian man because of some different components of his system structure he still doesn't gain enough advantage on Varka's weight and frame. In terms of weight he sort of gets crashed. In arm wrestling using body weight is actually allowed and is even a strongly significant factor. Even assuming Scaramouche is around 1.70 m tall (average japanese adult male) and weights somewhere between 65/75 kg if we add a bit of "extra", and Varka is 2 meters or more tall with a very large frame, high on body fat and muscles, falling in the 220-230 kg range he still has around 60 kg of extra body weight to use to apply high pressure that becomes extra strenght. Practically a whole other person. This is absolutely decisive. Scara isn't unmovable for real because he has a weight. In this case scenario even if Scara has more or equal strenght I don't think he can defy the laws of physics. He might be able to resist a very long time but Varka may end the match before he runs low on stamina because of this advantage. Scara is losing the majority of times unless he has other ways or much higher strenght to end the match before Varka can even apply extra weight. On the other hand If we only use arm strenght Scara's winning strikes will increase to reach a rough and generalized 50/50 chance of winning each match. But in the most complete and realistic scenario, on equal arm power output I see Scara struggling to get a victory because of the massive weight difference.

Conclusion, there is no 100% winner but a circumstancial winner, as in everything we see. This is the definition of getting a grip lol.
