Device Adjustments: Reduce Bids if high cost with conversions < minimum

[Czarto]

** File **
Adwords-Scripts/device-bid-adjustments.js

Desctiption
If a particular device does not have enough conversions to trigger a bid adjustment, but the cost is "high", then lower the bid anyway.

Proposed Solution
Set a user definable "COST TOO HIGH" threshold at which to trigger the bid reduction.

Alternatives
Is there a way to infer "COST TOO HIGH" from past conversion data?
