Usage of comma vs dash

Question

Which sentence works best in regards to ',' or '-'?

If you don't, the track record will become diluted

or

If you don't - the track record will become diluted

Answer 1

Use the comma. Dash denotes a break in the thought or an definition association. Better yet, use "If you don't, then" to show that the following portion is a causal outcome of the lack of action.

Answer 2

Definitely the comma, it sounds more natural and makes a softer pause in speech whereas the dash would be too sharp for this sentence.

Answer 3

Definitely the comma. The second clause is the direct consequence the reader is expecting to follow the first. A dash would suggest something more distinct.

Answer 4

I would say in that sentence, use a comma. Or, if you wanted to expand on that sentence, you could use a semicolon (;) and say, "The track record will become diluted; and if you didn't..." and whatever you would put after that.

I hope this makes sense!
