  The Non-Modal option has the advantage of ensuring that Retentionalist specious presents feature change and succession with maximal phenomenal immediacy – important for those who subscribe to the Immediacy Thesis (see §3) – but it also brings a serious disadvantage. To bring this out, let us suppose a single specious present has an apparent duration of around one second, e.g., enough to encompass two brief tones ‘do-re’. Since Retentionalist specious presents supposedly form a close-packed continuum, over a period of (say) ten seconds of ordinary objective clock-time, we will be experiencing content with a subjective duration of vastly more than one minute. To simplify, if we suppose there are a hundred specious presents per objective second, in a ten second interval we will enjoy experiences with an apparent duration of 1000 seconds – enough (apparent) time to hear ‘do-re’ a thousand times. Non-Modal versions of Retentionalism thus suffer from a serious problem with surplus content: they generate more experience (or more phenomenal content) than it is plausible to suppose actually occurs over a given interval of experiencing.  For diverging views as to the seriousness of this problem see Phillips (2010), Lee (2014b), Dainton (2014), Pelczar (2015) and Grush (2016).
