Hi,
That looks like a fun workout. I've never tried splitting a playing card. That would be a hoot! I like using my timer for drills when the range is slow and I don't get interference. Feel free to post these range reports in the "Skills" section so more people will notice them and heckle you. Well, they heckle me anyway. But I deserve it.
The Mrs. and I just got back from church. I played my bass on the worship team and made a joyful noise. The kids and grandkids were in church with us today. It's so special when we take up a whole row.

Be blessed.
Thank you for your indulgence,
BassCliff
