We need to find the reason for the low sim_scores of the "spawn start method" and make appropriate changes to ensure that the score is increased.
The KP is from Lib Ref. A similar doc of the KP is "spawn and forkserver start method". The KP "forkserver start method" has a high sim_score but the "spawn start method" does not. The relevant screenshot has been attached.

The possible ways to approach the problem can be:
1) Check fullness_ratio of the header var
2) Check the penalty for header variant or KP
3) Check if the score is getting reduced in tagging_utils.py
