Yes definitely noticed that so I adjusted some parts to to equally distribute the intervals.

You can't make the first interval the same as the rest unless you charge the capacitor to 1/3Vcc at power on. Similarly, you have to modify the reset circuit to discharge the capacitor to insure the first interval will be the same as the rest.
Although the tactile button messes it all up. It stops the timer but pressing it again wont turn it back on. I have to disable then able the power to make it work again
