Is the "flop to river" column in the odds chart useless?

[teddyFBI]

I got into a discussion with my friend yesterday about odds chart, and I was telling him that I thought that the column of the odds chart that tells you what the odds are on the FLOP that you'll make your hand by the river (i.e. 2 cards to come) was essentially useless.

Am I wrong? I've always thought that it was more accurate to simply use the "flop to turn" column when deciding whether to call a flop bet, and the "turn to river" column for a turn bet...in fact, I think that it's even misleading to consider the "flop to river" column, because the landscape can change so drastically on the turn -- isn't it best to think of things in terms of 2 distinct and separate decision points, rather than a single decision point with 2 cards to come??

I suppose that knowing that your OESD or 4-flush on the flop will come in approximately 1/3 of the time by the river is a handy tidbit to know, but when (if ever) is it really useful to consider the flop to river column in an odds chart?

Thanks
