I could only stake one block in 2 weeks, with around 200 CLAM
What size stacks did you have the 200 split into?
Since he only staked once, it doesn't really matter. Even if the 200 CLAM was in a single output the one stake will have frozen it for 8 hours only, so he was still actively staking for 13.6 days of the 14.
Seems like a better option would be to split that 200 into smaller amounts say 10-15 in size and allow for a month to pass. Having a large stack locked up for 8 hours seems like a waste
