instead of stating the obvious, maybe explain?
every item that you tek can either go up or down by 10, unless it starts at 0.
ex:
worst stats: 5/0/0/-5/5
best 25/0/0/15/25
only accept the tek if it is the best ^.^
Then there is the matter of common weps. Their specials go in tiers as well
ex: dim, shadow, dark, hell
say you find a Gatling and it teks with dark. odds are it can get tekked up to hell. anything with pink photons isn't likely to get the high end specials, red and yellow are your best bets.
