With a bicarb startup you maintain a +0.5 CSI for 3 weeks, then lower the TA to the recommended levels, the goal being to oversaturate the water with calcium carbonate in attempts to make a smoother, longer lasting and more durable finish. Fresh plaster (<28 days old) has not fully cured and is susceptible to the effects of aggressive water.
I recall you saying earlier that you were going to go with the bicarb startup for your pool. If thats still your intention then you'd only need to maintain a pH of 7.8 for the next couple weeks. Once that time has passed, you then can begin to lower the TA.
