Just to echo, doing high volume doesn’t necessarily put you deep into the TSB (if you’re already HV). I’m in the 3rd week of SSB1 HV and I’m currently at CTL 75 TSB 0, but I maintain 10-12hrs/week all year. It’ll probably be in SSB2 where I get pretty negative with TSB but following the TR high volume plans all year did not put me into a deep hole.
