We had 19 participants undergo 2 conditions and collected 6 measurements (5-min separated) for each condition. We have analyzed our data with an ANOVA repeated measures for within factors. Now we want know what the power was (post-hoc). However, it is unclear to us how to properly fill out all required fields in G*Ppwer 3.1.2.

Specifications
Test Family: F tests
Statistical test: ANOVA: Repeated measures, within factors
Type of power analysis: Post hoc

Question
We are not certain what to fill under
*Number of groups: Many examples we found on internet indicate that groups need to contain different participants, which is not the case for us.
*Number of measurements: It seems reasonable to fill out 12 (2 conditions * 6 measurements).
*Corr among rep measures: Here we took the average Pearson's correlation coefficient (r) among all measurements.

Thanks in advance for your feedback.
