It is not at all uncommon. Especially for mid seniority types. PBS will fill you up to the limit and as it tries to fit stuff in, the trips become less and less productive. It sees the 30 break and 12 in base as goals, not limitations.

All of this goes on BEFORE your PBS bid requests are even considered.

Again, during indoc, query them all you can about coverage awards. From the months of April, June, July, August, (sometimes September), November, December (and sometimes January) you will have very little influence over your schedule and with short staffing, no real way to change it the result.

Probably the best option is to be in the top 15% where coverage never reaches you, or bottom 10% where your schedule is so inefficient that you get some time off (and are just happy to be a XXX pilot).
