WOTC - Journey of four segments

I asked this question in the Wisdom of the Crowd:

Is it acceptable for a public transport journey to take up to four segments?

Here are the responses:

49 % - It is all right, provided that the walking distance to make a transfer is short.
26 % - It is better to make the transfer at the same bus stop.
14 % - The transfer from one line to another may take a long walking distance.
11 % - The transfer from bus to train and from train to bus can be quite a distance.
