Having some problems with preconditioning and free block counts.

[CC-0805]

Hello. I'm trying to modify some garbage collection schemes.

I found that GC activation is earlier than I expected and free block counts got smaller values compared to those supposed to be.

For example, with <Initial_Occupancy_Percentage>50, and 1chip-1die-1plane-16384 blocks

It seems that only 494 blocks left right after the preconditioning.

The log was printed in Flash_Block_Manager::Allocate_block_and_page_in_plane_for_translation_write and GC_and_WL_Unit_Base::handle_transaction_serviced_signal_from_PHY().
The values are plane_record->Get_free_block_pool_size() and pbke->Get_free_block_pool_size().

Is there any misunderstanding on my part?
