I know of the highest possible top 5 pokemon in all stats for each stat as shown here
http://www.arkeis.com/basestats.htm
and with EV training they can max out said stat,
but that website also mentions some discrepencies of pokemon with hold items surpassing the pokemon listed as top tiers for base stats such as:
"Note that a Medicham with Pure Power has a max attack of 480.
A Marowak with the item Thick Club has a max attack of 568.
All Pokemon with the item Choice Band will have their max stat increased by 50%. For instance, a Salamence with 405 Attack will have its Attack increased to 607 by using a Choice Band"
after reading that, i noticed that
The Marowak with the thick club had higher attack than Attack deoxys at a max attack stat of 504
there are also other discrepencies for other stats.
my question is, are there other discrepencies i should know about? is that all there are? are there more? if so can somebody please list them? preferable for as much stats as possible.
