Hi Leigh, I also use a windicator, but I use it as a visual aid to very quickly put the boat close to the line after a tack. From there I use the jib tells to show how high I can sail. After the start, I pay little attention to "true wind" as you are always sailing to apparent. Well, I'm watching the directions of puffs...
As to the angles remaining the same, no. If boat speed or wind speed changes so does the apparent wind angle (at typical sailing angles).
