Vehicle Count Modifier

[xybolt]

When you have a public transportation line, you can configure (or micro-manage) the number of vehicles on it. For example you can manage the # of bus available on a given line. That is done by adjusting the "vehicle count modifier" slider in "line details" info panel. Yet I have noticed that on a given line, it is possible to get eg 5 buses at 55% and 65%. When the slider is at 66%, the number of vehicles in use becomes 6. Similarly with 54%, which gives 4 buses.

Now, I am curious about something. Does it matter at which %, within the 55 and 65 range I have dragged the slider to? I tried the lower bound and then the upper bound for a while and I do not see any notable effects.

So my question is, should I slide it to the lowest %, 55% in this scenario or does it have a negative consequence(s) towards setting it on 65%? The positive effect is ... I think that I have a lower expenses per week when I set it to 55%. But I have a feeling that it might have the same effect as tweaking the %'s in the budget panel, for example for energy.

Did someone have experimented it before? Or does it not matter?
