> The type is changed from int32 to double, is there some reason?
Yes, we can test cases of percentage with more accurate values, such as 0.1, 
0.01 and etc., to simulate the low live block ratio in real world.

I want to delete FLAGS_startup_benchmark_deleted_block_percentage percentage of 
block ids, but in your way, it seems only 
FLAGS_startup_benchmark_deleted_block_percentage/FLAGS_startup_benchmark_batch_count_for_testing
 percentage of block ids can be deleted, right? It can't jump in the for loop 
after j >= to_delete_count_per_batch.
