vowel indicator omissions, help

I am having a problem reading some of the material in Gregg Anniversary.  What causes it is the omission of the vowel indicators, such as the word Day: d-stroke, a-circle, but no dash indicating a long-A sound. (i hope that makes sense.)

I know why it's not put in, for speed, but it's buggin' me :)  As a former court reporting student, I'm used to the schwa syllable not being included.
I'm sure I'll get better with practice, but does anyone have any hints to help my read back?  As with court reporting, if you can read it, you can write it.
Thanks in advance,
