I’ve always wondered whether the easier option is just to gradually increase the ACR ratio beyond what it is now as weeks on chart increase …

We’ve seen from the album chart having a high turnover that it does incentivise interest in the charts. E.g. James Blunt this week.

Don't see why the calculations need to be easy to understand. I'd rather they made the rules more complicated but resulted in a "better" chart.

If the way a chart is compiled is easy to understand then joe public will want to understand and follow it and more people following it means more people noticing the new entries and getting them a bit further up the chart the next week etc. When the chart was essentially straight sales figures, with no streaming involved, then it was clear what it represented and therefore clear that it was definitive and meant something. Nowadays the chart rules are so complex that it has really got to the point that it barely means anything anymore because, as someone else said, the OCC could just be pulling the figures out of their ass since they don't directly correlate to anything in the real world now (even checking Spotifycharts won't help you know for sure where any given track ought to be in the OCC chart, what with ACR, three tracks per artist rules, uncertainty about what is or isn't reset in terms of older tracks, different ratios for different streaming services and for different groups of user within the same streaming service, and artists (or their management) deciding for themselves when to mail out pre-orders, and how many of them to mail out each week, for best chart advantage, when really all pre-orders should probably just be acrued to the first week of release). I just feel that if the chart represented something more meaningful and tangible then more people would follow it and more songs would get noticed and climb up the charts, improving turnover. It feels like the OCC's priority in the last decade or more has probably been to make a chart that no other company or market research body could ever replicate, thus ensuring no-one can check their workings and no other company/research body can get in on the act and sell a truly comparable chart to theirs instead of them selling their one, but that same process that ensures the OCC have a unique chart product also erodes the actual meaningfulness of the chart and the interest in it.
