i could probably google this but i figured id post it up here incase someone already knows and can answer my questions directly

so i drive a manual
and i noticed that when im in 3 .. if i accelerate past 3 r/min and take my foot off the gas there is a brief moment somewhere between 2-3 r/min where i can put it in 4 without using the clutch at all.

this only seems to work in gear 3 when going to gear 4

does anyone have a legit explanation why this is possible?
also if the r/min is below 2 then you cant do this .. its gotta be above 3r/min and as its declining you can slip it in to 4 without the use of the clutch
