Outs on the turn & river

Looking for a reliable source for an "outs" table for the turn & river. Ken Warren's table shows a declineing chance of hitting from the turn to the river. Meanwhile, Matthew Hilger's book says the odds are slightly better when drawing on the turn because on more card has been exposed. Also Warren's book dosen't convert %of probability to odds. I did the math but the odds don't exactly match Hilger's book or a chart I got at on the net. Thanks for any help.
