Is it normal for a ti coil to raise approx.1 ohm after break in? It seems that every coil i build will be rock solid for a day and then jump .1 ohm higher. After the jump it stays stable at that ohm and i have to adjust the temp and wattage to get the vape I like.... For example, i built a 28g parallel coil two days ago. 8 wraps at .18 ohm two days ago. vaped it all day at 55 watts 480f. Yesterday when I woke up it jumped to .28 ohm and i had to raise the watts to 85 and temp to 530f to get the same dense warm vape. Not getting any dry or burnt hits and has been rock solid since then. Anyone else have the same experience?
