Please post a reply instead of changing the initial post next time, to avoid confusion.

To calculate the average of an alternating tempo, you can do several things:

1. Compute the average of the tick speeds (4 in this case) and set the initial speed to that value, then do approximation while playback is stopped. This only works if the average is not a fractional number, because tick speeds are integers.

2a. Otherwise, change the initial speed/tempo values to 3 and 5 respectively and do the approximation while playback is stopped. Note down the results.

2b. Alternatively, use "Play Row" to start playback (but not advance playback) on a row with F03, approximate BPM and then repeat the same thing on a row with F05. This works because BPM approximation uses the current speed and tempo if playback is running. Note down the two results.

After you have done either 2a or 2b, you simply take the average of the resulting BPMs.

If the pattern is not as regular (let's assume 3 rows of F03, then four rows of F05 as a random example), you would have to weigh the results accordingly, i.e. (3 * (BPM at F03) + 4 * (BPM at F05)) / 7.
