PA Change Success Score JOb

Need to understand about the Data collector JOb which comes under package Change management change success score,There is a JOb named " CHange success score for today",it is an on-demand job and neither its daily nor historical,i just want to know what type of job it is and should we make them active or leave as its is and someone will execute and collect the score from specified fixed date for 12 month or this job is something different,What will happen if we customize it to monthly instead of on demand
