For one, you are ignoring the fact that it is part of a bigger project that will eventually take into account somehow that Machamp hardly if ever uses Special Attacks.
For two, this isn't about "i want a sweeper". This is about "i want a good overall Pokemon with overall good distribution" as it is. Stat distribution isn't everything, however. This is only part of the process.
Darn, and I so adore my Fire Blasting No Guard Machamp. Screw you Forry, Bronzong, and Skarm >_>
Yeah, this is a lot of seemingly unneccesary math, but one thing I found interesting was bared out in the topic about Diminishing returns on HP/Defense.
It seems here that even if you have awesome offensive stats and speed, but get slaughtered in one hit you each a low rating. Wheras if you have high speed and decent defenses and attack power (e.g. are a powerhouse that doesn't get owned immediately) you score high.
I found Mewtwo's placement at #2 quite interesting. Lugia was just behind at #3, and Ho-Oh was #8.
Thing is, these pokemon have the exact same numbers in their individual base stats. Ho-oh actually took a hit because he had higher offenses than Lugia but lower defense and speed. Lugia took a hit because even with it's blatantly superior defenses and still high speed, it fell just short because of low offenses.
Now look at Eeveelutions, who share the same phenomena of a 130/110/95/65/65/60 BST.
Vaporeon is at #71.
Umbreon is at #73
Espeon is at #77
Glaceon is at #81
Leafeon is at #83(just below Glaceon, which ties with P2 at #81)
Flareon is at #86
Jolteon is at #97
I find it interesting that Jolteon is actually the lowest. It has the highest stats in speed and SA, decent SD, and its physical stats and HP suck.
Espeon on the other hand has the same HP, attack, and S/Def stats as Jolteon, but with Speed and SA reversed. It moved up 20 spots on the list.
Vaporeon and Umbreon are the most defensive on the list. That massive HP does wonders for Vappy. Interestingly, its 110 base is in SA. I wonder where it would rank if it were 110 in SD and 95 is SA.
I think these are the most valuable analyses since they are the exact same specific numeric values, but placed in different areas. The Espeon/Jolteon rift is interesting to say the least.
