Given the almost permanent downswing experienced over the previous 6 weeks to the end of February, the 1st week of the reset challenge has to be viewed as reassuring progress, as it has been a week of playing breakeven poker, which was the baseline target for the original challenge.
I've played 6,885 hands in the first 6 days of March, with a cash loss of $25.29, but with an EV loss of only $0.59, so the $25 is adverse variance (and a relatively small number compared to the February experience).

The first few days were PLO5 and PLO10 only, which confirmed that on 1,000 hands per day of volume, I would fail to hit the points target for the $200 monthly rakeback challenge, so I've realised that I need to add in PLO25 play to address this. I've done this on a limited basis so far, and it's been successful, but any kind of downswing would put huge stresses on the starting bankroll, so I'm proceeding with caution in this regard. To date, the volume split has been 3k hands at each of PLO5 and PLO10, and 800 hand of PLO25.
The bankroll pressure will ease if I can hover around the starting bankroll level for enough time in March to hit the bonus chest targets. If so, then we should be starting April with something like a $500 balance, which is much more comfortable (albeit still not immune from a repeat of February's experience). However, in recognition of the risks, I'm treating the starting balance of the new challenge as being $500, of which the residual $300 won't be deposited until or unless required. If I can avoid making the top up then I'll treat it as a small mental victory, but this change is essentially a recognition that the current rakeback targets for March can't be achieved without PLO25 being included in the mix and, with the change from 50BB buy-ins to 100BB, $200 would be an extremely short bankroll to attempt this.
From a general play perspective this week, I've been happy with the minor changes that I've adopted as part of the 'reset'. The most significant of these has been to focus in-play on the All-In EV result for the session, rather than the actual result. Mentally, I'm trying to keep this figure at or above break-even in each session, rather than focusing on the actual result. Although there are glitches in the way that HM3 calculates this I can also monitor these more closely by following this in-session.
I spotted one such issue in the first session played during the month where there was a multi-way all-in hand that didn't register a percentage in the result, so wasn't factored into the stats. However, it was one of only two all-in hands played during that session and I realised afterwards that HM£ still takes this into account in the average EV for the session reported in the stats, where it is counted as 0%. Consequently, I was more relaxed about my average all-in equity for the session showing as something in the mid 30%'s when I'd realised how this had been calculated. The hand in question was one where I had 60% equity on the flop when the first player goes all-in, and then 19% equity when the remaining money goes in on the side-pot to leave me all-in, so I appreciate why this is not a straightforward calculation for HM3 to include in the adjusted EV stats. However, to have it count as 0% within the session averages calculation is something of a glitch which I'm now keeping an eye out for.
Whilst being a very small sample of sessions so far, the new approach seems to be better in terms of tilt control. I've had one session to date which was circa $50 below EV (not great on a $200 bankroll) and focusing on the All-In EV result allowed me to continue playing without a noticeable tilt mid-session as this accumulated. Additionally, trying keeping the All-In EV number above zero as a focus for each session is also making me consider post-flop decisions with a greater focus towards it, and I think this is eliminating some of my earlier leaks in this regard. I certainly feel like I've played far more consistently over the entire week than I have done for a while, regardless of whether the session has been a winner or a loser.
I've also managed 3 cashes on the leaderboards this week, with a very near miss on a 4th one (I went to bed showing as being in 20th place, which didn't survive). However, as these were all minor placings on PLO5 and PLO10 leaderboards, the sum total of all these cashes has been a whopping $9. Better than nothing though.
So a good week overall from a mental game perspective. The results may not look spectacular from the graph, but there are a significant number of positives to be taken from relatively minor tweaks having been made to my approach and my play. Hopefully, I can continue this progress throughout March. If so, this should be sufficient to get me to a point where the bankroll is in a much more secure position for the scale of the overall challenge.
