If the developers documented (document) the API properly, we would finish (finish) the integration much faster. (type 2)
If the developers had documented the API properly, we would (could, might) have finished the integration much faster. (type 3)
“…we ____ (finish) the integration much faster.”
This refers to something already completed or too late to change. Because we’re talking about a result that didn’t happen, the first conditional cannot be used
