+The value 240 is derived from the fixed size of the pc_price_t struct excluding the size of the comp_ array.
+Here is the breakdown of the sizes (in bytes) for each field within the pc_price_t struct:
+
+- magic_ (uint32_t): 4 bytes
+- ver_ (uint32_t): 4 bytes
+- type_ (uint32_t): 4 bytes
+- size_ (uint32_t): 4 bytes
+- ptype_ (uint32_t): 4 bytes
+- expo_ (int32_t): 4 bytes
+- num_ (uint32_t): 4 bytes
+- num_qt_ (uint32_t): 4 bytes
+- last_slot_ (uint64_t): 8 bytes
+- valid_slot_ (uint64_t): 8 bytes
+- twap_ (pc_ema_t): 24 bytes (3 fields of int64_t each taking 8 bytes)
+- twac_ (pc_ema_t): 24 bytes (similar to twap_)
+- timestamp_ (int64_t): 8 bytes
+- min_pub_ (uint8_t): 1 byte
+- message_sent_ (int8_t): 1 byte
+- max_latency_ (uint8_t): 1 byte
+- drv3_ (int8_t): 1 byte
+- drv4_ (int32_t): 4 bytes
+- prod_ (pc_pub_key_t): 32 bytes (assuming pc_pub_key_t is a 32-byte array or struct)
+- next_ (pc_pub_key_t): 32 bytes (similar to prod_)
+- prev_slot_ (uint64_t): 8 bytes
+- prev_price_ (int64_t): 8 bytes
+- prev_conf_ (uint64_t): 8 bytes
+- prev_timestamp_ (int64_t): 8 bytes
+- agg_ (pc_price_info_t): 32 bytes

+Adding up all these sizes gives us a total of 240 bytes for the fixed part of the pc_price_t struct.
+The size of the comp_ array is variable and depends on PC_NUM_COMP, hence it is calculated separately and added to the base size of 240 bytes.
