=== Preservation quality ===
While ways to quantify the quality of preservations have been proposed, notably by [http://www.oregoncryo.com/qualityScores.html OregonCryo], there are currently no systematic analyses done about the quality of current preservations. The following graph is an attempt to track progress of cryopreservation techniques by tracking the biggest mass that was successfully cryopreserved.<ref>{{Citation|last=RomanPlusPlus|title=SPTCR: curated repository of scientific papers on cryonics: RomanPlusPlus/scientific-progress-towards-cryonics|date=2019-01-11|url=https://github.com/RomanPlusPlus/scientific-progress-towards-cryonics|access-date=2019-01-23}}</ref> It doesn't directly track what cryonicists care about, but can be used as a proxy while better metrics are developed.

=== Tracking preservation quality ===
An interesting addition that could be done to this page is to measure the progress (if progress there is) of cryonics cases. If you're interested in contributing to this project, you can fill the columns related to the quality of the cryopreservation in the Google Sheet [https://docs.google.com/spreadsheets/d/1vBrlNvPkPQbLKxtSUlTF_ZpUS4lwW2W7lENRj9Gdk3I List of cryonics patients] by going through some of the cases published by the cryonics organisations; see: [https://alcor.org/cases.html Alcor (human cases)], the [https://www.cryonics.org/case-reports/ Cryonics Institute (human cases)], [http://www.oregoncryo.com/caseReports.html OregonCryo (human cases)], [http://www.oregoncryo.com/caseReportsPets.html OregonCryo (non-human cases)], [http://kriorus.ru/Krionirovannye-lyudi KrioRus (human cases)], [http://kriorus.ru/Zhivotnye-kriopacienty KrioRus (non-human cases)]. While ways to quantify the quality of preservations have been proposed, notably by [http://www.oregoncryo.com/qualityScores.html OregonCryo], there are currently no systematic analyses done about the quality of current preservations by any of the cryonics providers. As for the improvements done in laboratory conditions, progress is better tracked by noting various discrete technological development as done in the full timeline above. While having a graph tracking the [https://github.com/RomanPlusPlus/scientific-progress-towards-cryonics "biggest mass of a successfully cryopreserved tissue/organ/organism by year, kg"] is appealing, it doesn't meaningfully track progress done on brain preservations which pose a series of challenges not present in smaller volumes of tissue as [https://drive.google.com/file/d/1eGVzwmr1TDgN9HnDfTZNnzP98-hipHoc/ noted by Mike Darwin].
