Cylinder 4 timing drops

Here is a timing log for a 3 gear pull. Cylinder 4 is dropping timing for some reason.

Logging advice. Log timing on cylinder 1, and correction on all cylinders. Makes it easier to read.

What is the magnitude of the drop?
What map are you running? fuel? how old are you spark plugs? etcc...

When using VD to post logs its important to have the curser over the important part so we know the values. Also, posting up the CSV as a TXT is always helpful.
