Imagine the items with index 0 and 1 are both >90 and step through the
code in your mind.

After the item with index 0 has been deleted, the item with index 1 now
has an index of 0 - so when you move to the next item (index 1), you've
skipped one.

Two solutions :
1. only increment idx when you do not delete one
2. start from _someList.Count and work towards index 0
