Yeah totally not buying the Chillaccino=Ambipom argument. Because Ambipom has Rock Blast/Sweep Slap/Bullet Seed right? The only problem is deciding between Technician and Skill Link in DW unless someone clever has bothered to do average base power checks of course.
Well, to start, the probability distribution of these moves is:
2 Hits: 37.5%
3 Hits: 37.5%
4 Hits: 12.5%
5 Hits: 12.5%
If my mathematics are correct, the average outcome of these moves without using Skill Link is:
2*.375 + 3*.375 + 4*.125 + 5*.125 = 3.000 Hits.
Ergo: The average base power of Rock Blast or Bullet Seed using Technician is Base Power * 1.5 (Technician) * 3 Hits = 112.5BP. Tail Slap/Sweep Slap gets STAB on top of this.
However, note that even though this is an average, you actually have an equal chance of scoring 3 hits as you do 2 hits. Therefore, even though the average outcome is 3 hits, you only have a 3 in 8 chance of this. Technician will outpower Skill Link if you get four hits or higher, but you only have a 1 in 8 chance each of getting 4 or 5 hits.
Comparing this to Skill Link, which has 100% probability of having a 125BP move (187.5 for Tail Slap), I don't actually see the purpose of using Technician at all when Skill Link is released officially - nor do I see the point after that in using Wake-Up Slap to cover T/Tar.
On the other hand, Wake Up Slap is the only Fighting move Chillachino learns, so....
