Why 11 minutes stopped (ntptime shows errors) when we add "tinker step 1 panic 300" in ntp.conf

Issue

When we add "tinker step 1 panic 300" in ntp.conf, ntptime shows the following error like https://access.redhat.com/solutions/38542

# ntptime 
ntp_gettime() returns code 5 (ERROR)
  time e2ad21ad.02b9c304  Mon, Jul  6 2020 13:06:05.010, (.010647935),
  maximum error 16000000 us, estimated error 16000000 us, TAI offset 0
ntp_adjtime() returns code 5 (ERROR)
  modes 0x0 (),
  offset 0.000 us, frequency 0.014 ppm, interval 1 s,
  maximum error 16000000 us, estimated error 16000000 us,
  status 0x2041 (PLL,UNSYNC,NANO),
  time constant 3, precision 0.001 us, tolerance 500 ppm,

Does this mean as same as when adding -x option (https://access.redhat.com/solutions/38542) ?

Does this mean that 11 minutes mode stopped ? https://access.redhat.com/solutions/2455681

The default behavior is said that it is same with "tinker step 0.128 stepout 300 panic 1000" and 11 minutes mode is enable

But, form the above behavior, when adding tinker explicitly , Does this mean that 11 minutes mode gets disabled?
