first off, the sports teachers do not care if they have n days between activities with the same group, they only want their classe not to overlap more than 2 sports teachers at the time. besides, i do need some gaps in timetables for 2 reasons:
1- teachers have a number of lessons a week, and a number of hours they have to be present at school. if i don't give them any gaps, they will feel horrible if they have to stay longer after classes. it's less painful if they have gaps
2- I need to give 3 additional hours to each teacher for substitutions. I need 4 available teachers during all the hours when students are at school. these teachers will only be there, and go to a classroom if some teacher is ill, or needs help.
I hope this explains your doubts. The law is very strict on those subjects over here
