Hello and thank you for such a great application. I wanted to know if setting the age in the CPP and OAS section has any impact on the CPP/QPP and Withdrawal optimizer? Should I pick my preferred age (say 70) or just set it to 65 (both OAS and CPP) for both my spouse and I and let the Optimizer pick the best age? Once I have that age from the Optimizer (assume 67 for both) should I update the ages in the CPP and OAS section? Hope this makes sense and thanks.

The only impact your current settings have is that they set the scenario that the results of the CPP/QPP and Withdrawal optimizer will be compared to (when showing you the difference in liquid legacy).

This optimizer will go through all combinations of ages and show you the best one, so your current settings in the CPP and OAS section don't matter, and you should probably set them to your preferred ones.  If the tool finds a better result, it will not change your settings automatically. We leave that up to you to decide if you want to change your preferred ages to use in future runs of the TIME MACHINE.
