What's your lpm with gsa

Hey guys,
I'm looking to know what is a good LPM for GSA with 10 proxies and captcha breaker for spam tier and captcha breaker with death by captcha for contextual links. Also 100 treads and HTML 50
I m getting for spam tier 3 LPM 20
for Tier 2 contextual link LPM 2 which it looks pretty bad
Any advice to increase LPM
Thanks

I use 20 proxies and only CaptchaBreaker. I usually get around 50-70 lpm.
