I see what you mean, but my problem with that is Goku trained under regular Earth conditions and got stronger, too, as did Tenshinhan. Sure, Goku trained with Piccolo and Gohan, but his non-SSJ form already dwarfed them, so how could they have been useful? And sure, Tenshinhan trained with Kaio and under 10g, but Krillin had his potential released by Saichoru, so even if Tenshinhan got much stronger, his holding back semi-perfect Cell shows it's plausible that Krillin could do similar with Freeza.Bussani wrote:Of course, just being able to endure harder training probably isn't enough. Kuririn made great strides training at Kami's Palace under Kami himself and Popo because they're good teachers, because the lookout itself has conditions you need to adapt to, and because he had a lot of room for improvement. It was probably the best place to train on Earth until the Room of Spirit and Time was revealed. Once Kuririn mastered the training there, the increases in strength probably declined rather than progressing linearly. To make matters worse, Kuririn came back from Namek much stronger than that. Finding a sufficient training method on Earth by that point would be a challenge, I think.Dayspring wrote:That's a 4.16x increase. Assuming it's like that for every 10 months of intense training, and assuming the "close to four years" for the three years of training was 40 months, that means Krillin went from "over 10,000" to over 2,994,837. That's ignoring the fact that the stronger you are, the harder you can train (meaning the increase should be larger than 4.16x for each 10 months).
In short, I think going from a low level to a medium level under Earth conditions is easier than going from a medium level to a high level under Earth conditions.
As for your comment about Tenshinhan being there for days, they were actually with Kaio for 260 days (Yamcha for 130). Still much less than Goku, but they're being stronger just means it didn't take as long to travel Snakeway, so they pretty much got the same amount of time with Kaio as he did.
