Correctly using sticky bit with restriction rules

Help!
1

I have some questions about my haproxy config.Please help me and check my sticky bit rules , thanks for attention!

  1. should “sc_http_req_rate(4)” match “track-sc4” ? Both should have 4 ?
  2. should “sc_gpc0_rate(0)” and “sc-set-gpt0(0)” and sc_get_gpt0(0) match “track-sc0” ? Should both ends be 0 ?
  3. should “sc_http_req_rate(2)” match “track-sc2” ? Both end should be 2 ?

Here is part of my haproxy config

backend per_ip_rates #sticky tables detecs src ip in
 stick-table type ip size 1m expire 15m store http_req_rate(10s)

backend per_ip_rates2
  stick-table type ip size 1m expire 2h store gpc0,gpc0_rate(10s),gpt0
  
backend per_ip_rates3
  stick-table type ip size 1m expire 24h store gpc1,gpc1_rate(30s),gpt(2),http_err_rate(5m)

backend per_ip_and_url_bruteforce #for level 3 section protection  
  stick-table type binary len 8 size 1m expire 10m store http_req_rate(3m)
