or the yellow 'hint' how far you are is wrong? 

correct: 
take a cell formatted as 'number - standard' 
key in '-307', 
click the small black square bottom right corner of the cell and pull down some rows, 
observe a small yellow hint telling you which value will be filled in the last cell, 
release the mouse button and observe appropriate fill, 

fail: 
take a cell and format it to '@' - 'text', 
(do not! only change the format of the previously used cell, it will fail - to fail - unless you at least do a 'non changing edit' or similar as 'formatting doesn't adapt value' (a big pitfall imho)), 
key in '-307', 
click the small black square bottom right corner of the cell and pull down some rows, 
observe a small yellow hint telling you which value will be filled in the last cell, 
release the mouse button and observe opposite! of appropriate fill, (filling downwards, despite the yellow hint told 'upwards'),
