Yes, this only shows pilots who will be integrated. The post-merger hires will be junior to all affected pilots from all groups and will therefore have no impact on the career progression for senior affected pilots in any merged scenario.

The data model presents outcome information based on highest ranked position possible for all pilots at all times. This doesn't happen in the real world but is extremely useful for building outcome results which are determined by known variables such as list order or conditions and restrictions while controlling the unknown personal choice variables. So while pre-merger pilots could choose to bid positions normally held by post-merger pilots, that is not a reflection of maximum bidding power and won't be included in the model. In short, the results indicate the best everyone could do from each group under both proposals.

Also as mentioned on the chart website, the data used to create the charts is an estimate from the submitted proposals. To be more accurate, specific inputs concerning inactives, job counts, etc. would be needed.
