Let's try to examine Tien's development.

-Even though it's filler,since it's the only piece of evidence about Tien's gains at Kai's,i'll use his fight with Jeice and
Burter.Tien's two halves were even with the two Freeza's soldiers(40k each),so i have this Tien at 80k.
-He stays at Kai's for a little more,rising to 100k.
-After his return on Earth,he does plain Earth training,without preparing himself for anything special.So,his gains are
now smaller and rises to 120k.
-The gaps between 22nd and 23rd Budokais showed that humans are capable of having 20x like gains in a 3 year
period.Over the following 3 years,Tien trains for the Androids,so his power could go to,like 2.5 mil. That made him
get carried away and think he could be of help against Androids.
-Over the following years Tien was left once more without any special purpose,so he went back to plain training.
Therefore,at Buu Saga,he should be at around 2x Kaioken Goku(post ginyu zenkai) or a little bit more.
