Not sure how you get that number, have you tried this fit?
Bulkheads are good on the Procurer, but the Skiff can get a strong shield tank with double LSE.
As this is my mining character he doesn’t have max fitting skills (and no reactor control unit II skills 
) so I can probably squeeze out more EHP by upgrading some skills to fit faction LSE.
Scales better with the shield bursts from the mining support ships too this way.
