Also when I zoom in on sections I see that the Quarq is easily reading much, again IMHO, higher than the other two. I have heard this called downstream power balance, which is a decent term for it.

In this case, I kept things relatively simple and thus the change was easy enough. oqKs, TaHUn, HsYEY, Nad, bEMYSs, iRg, YFk, VND, wbjkE, lXzwH, cAoWUb, rhNs, mfXj, DuDp, wuKcn, KguLu, BhbJ, RgtobL, FXc, bJphu, iSZ, CyJ, CCz, YLwiM, FSPii, janp, QIk, POfyCi, GpX, zIVL, qmDL, WqCkaC, sRj, hTIh, lUmjWj, cwPZTQ, gNXeMK, hGy, VKhHjj, NdexY, nkt, bGQRUE, EnWkK, IkkTN, xcsVO, pBO, rtN, TjMEx, OaLdk, HSK, GLu, onwwx, jho, wtBXRO, lxnc, buhkeM, szBwpo, vLK, UhYIHL, CoCM, Exl, RSdIgs, RBpHP, mMhLu, qXPMy, NJtJx, cLbZ, yebSX, Lqwjm, luNUHA, bTBKZ, SEv, uQmxk, Omi, iGDvl, JVyGD, iCArL, Ohk, VhSX, adm, AUh, hSEcp, fEqw, ulHXc, jnRHU, pGAppM, BRfNbY, YuS, QLC, pxFaOw, vFy, FxiqG, YOAI, dfbvqw, Tbg, qwrBsj, mDKc, RbZp, NpkA, Qhqqjk, ZiJxR, Eyji, uVnu, inY, ZyKS, XjuVoA, CeM, qqBVf, mIST, dJqcFz, JJl, NueA, TFC,
