off-topic: Since you obviously are interested in Unicode (you used • and even ␄), you could continue the trend by using ¹, ² and ³ instead of [1], [2] and [3].

off-topic: Since you obviously are interested in Unicode (you used • and even ␄), you could continue the trend by using ¹, ² and ³ instead of [1], [2] and [3]. For the corresponding explanation at the bottom, use ①, ② and ③. Also, instead of "worst case", write “worst case” (typographically correct quotation marks) and instead of ', write ’ (typographically correct apostrophe). In case anyone wonders how to enter them efficiently, I use neo-layout.org which provides ¹ on Mod3+1, ① with Multi_key + ( + 1 + ), “ with Shift+9, ” with Shift+0 and ’ with Mod3+0.
