Light curves of several semiregular and symbiotic variables from my program. Visual estimates together with data from ASAS-SN survey and CCD observations from AAVSO database. Some time visual data are useful (WY And), sometime the advantage of one visual observer is visible (CH Cyg), sometime visual data fill the gap in the survey data (TZ Cep), sometime visual observation are completely wrong (CK Vir).
