I think the new set up actually looks like this:
36 24 *12* 87 58 *13* 80 54 *14* 75 50 *16* 65 44 *18* 58 39 *20* 52 35 *23* 45 30 *26* 40 27 *30* 35 23 *34* 31 20 I would find a hi gear of 87 too low and a low gear below 25 unnecessary, but to each his own. Other than the big jump between the 14 & 16 on the big ring the shifting pattern is remarkably good for a 12 tooth difference and a wide range cassette. This gearing question has no perfect answer, just a bunch of trade offs between wide range and acceptable patterns. If it suits you, go for it . Quite creative. I ride a 44/30 with an 11-28 nine speed cassette and lots of people would find that.... unusual.
