# Inverse proportions, but the other way around [closed]

The title sucks, I know... Anyway:

As part of a game I'm making, one of the buildings decreases the time it takes to build other things. Like so:

At level 0: Full time
At level 1: Full time / 2
At level 2: Full time / 3
At level 3: Full time / 4
...

So basically, the construction time is inversely proportional to this buildling's level. But so far my sentence to describe this effect is:

This building reduces construction times by a factor proportional to its level.

Is this correct? Is there a better way to phrase this? By my understanding this means that the factor (the denominator of the fraction) is proportional to the level, is this correct? Does "level + 1" count as proportional?

• It would be a good idea to clarify the question. From the problem description, I don't understand the construction time equation or what is being constructed or who is contructing what. Is Mitch's statement correct? (with inverse replaced by inversely) Jul 19 '12 at 21:26
• I see someone voted to close as Too Localised. I've voted to close as General Reference. What's the opposite of inversely proportional? Proportional! Jul 19 '12 at 21:51
• So why can't you just say "inversely proportional"? It seems to me like the right expression.

It may be better to talk about construction speed rather than construction time. You can say: "At level k, widget construction speed is k+1 times as fast as at level 0." Alternately, provide a little table of construction speed, with entries like "Level 2: 30 units per day".
