sma's response to sharpeners last post is below! what does changing the cycle time achieve? I’d already assumed that you’d be using both strings (A+B) of the SB4000TL to get the best out of the E/W scenario using both MPP trackers.
Cycle time can be changed from 6min to 30min using Sunny Explorer.
The following link will show you how shading can affect your daily yields. The video is pretty good at explanation.

Best advice is to monitor your systems’ performance (Sunny Explorer is free). If you encounter yield curves that suggest shading issues, then Optitrac is worth trying. You could then compare the yields with/without Optitrac and then make a decision.
It may be that Optitrac really helps at the transition stage between E -> W as the sun tracks across your panels.
