Hi Jon, I can only speak to the functionality of the AdWords API, but in that regard if a user comes to your site twice -- once via Ad 1 and five days later via Ad 2, then the Click Performance Report<https://developers.google.com/adwords/api/docs/appendix/reports#click> will report two distinct *GCLID*s. In terms of conversion uploads, you could upload a conversion for each of those clicks, but if you upload multiple conversions for the *same* GCLID/conversion name/conversion time combination, AdWords will only record the first uploaded conversion and ignore the rest<https://developers.google.com/adwords/api/docs/reference/v201402/OfflineConversionFeedService.OfflineConversionFeed#conversionTime> .
I'm not sure if that answers your question, though. If you are asking about the behavior of the API, feel free to post a follow up here. If instead you are asking about the behavior of the *Model Comparison Tool*, then please post your question to the Analytics forum<https://productforums.google.com/forum/#!forum/analytics> .
