Tide high/low heights are incorrect

[cohenadair]

From user:

I noticed an error in the tidal values shown. I've attached two screen shots; one from Angler's Log and the other from a tide program I use (Tide Now AK). As you can see, the values shown are about 6' to 7' different for high an low tide values. The graph is pretty accurate, and the times are quite close but the tide height is off:

Low tide:
Tide Now AK, 11:24 am, -0.45' which is correct. Angler's Log, 11:22 am, -8' 7" which is about 8' too low

High Tide: Tide Now AK, 05:53 pm, 16.79' Angler's Log, 05:46 pm, 7' 10"
