It is difficult to come to conclusions without seeing it in action. I don't think it's doing any great harm, but it's probably not charging the batteries as quickly as they could be, so in many situations the algorithm will reduce the solar panel output.
I may be wrong but it seems to be doing a fine job. It reaches float voltage, a load is turned on and the regulator compensates by letting the appropriate amount of amps in to compensate for the load.

The appropriate amount of amps would keep the battery voltage constant.

0.4v is quite a large change, the current charging the battery will vary considerably with this voltage difference.

If 13.4v is an appropriate voltage at a particular SOC the regulator should maintain this voltage, irrespective of the load (if the solar output is sufficient).
