I think it might just be connected to the ‘ignored’ matter. Here is another example: If I do a Batch process on a set of cards, adding them to an existing score profile, and then setting their status to Review, then when back in the relevant flashcard test profile (set up same as above), again the score after the first time I am tested on one of these cards seems to be ‘ignored’. This applies whether the "Don’t show begin study for new cards” is set to on or off. Probably the latter setting is irrelevant here, because although the card is treated as ’new’ (at least it seems to be for the purpose of the ‘Max new cards per day’ setting), it correctly does not enter the learning stage.
I will explain my aim here. I was originally using two different test profiles, including a Pleco4 learning profile for new cards, and a legacy profile from Pleco3 successfully imported when the beta came out. However, I have ignored the legacy profile for ages so all the cards there are now due review, but I know them quite well anyway. I wanted to combine these two test profiles into just one test profile going forwards, with something like the following behaviour: new cards would be prioritised via Pleco’s spaced learning, but at least part of the time (perhaps when I set the max cards to large) Pleco would automatically present some old learned cards to me for review (including ones from my legacy set). After correctly answering one of my old cards under review, I wouldn't expect to see it for a long while, but instead it would come back straight away! (And I guess this is because the score was ignored.)
For info, I think I have successfully achieved something like the above in two different ways now, one by playing with the test settings including priority etc., and now also via the batch process mentioned above. I think so anyway, although probably I should run this out for a few more days. But in both cases, the ‘ignored’ test result means I always have one unwanted extra test per card!
(PS I might be muddled about this! Also, I am having fun messing with the above, and am writing it up here only in case it is useful feedback.)
