Don't worry about the brief fluctuations in gusty winds. The baro is a mechanical device and does not respond instantaneously.
Also, the baro calibration marks are just a rough reference, not a precise setting. Adjust the baro to give the desired manometer reading, since the manometer IS more of a precision device. If your target is .05, and the manometer says .05, then you are good regardless of which mark the baro weight is at.
If there is a BIG discrepancy between the baro setting and the manometer reading, then you might have other issues such as a deficient or too-efficient chimney, improperly placed baro, improperly place manometer, etc. etc. If so it's probably best to address that in a new thread.
