<div>Hi all,</div>
<div><br>
</div>
<div>I agree! The quality of the experiment will benefit dramatically without the rushing! And everything that's learned and developed during GMn is directly applicable to GEn-RP. And all of the Npol analysis can be developed before the run.</div>
<div><br>
</div>
<div>Also, even though GEp is not yet scheduled, it will be much more of an immediate sequence, which makes that experiment better, too. </div>

<div class="PlainText">Hi Brad,<br>
<br>
Many thanks for the update. There is no doubt we will do a much better measurement in 2023. Given the difficulties with GMn I feel that this is definitely the right decision.
<br>
<br>
Cheers,<br>
