Welcome!!<br /><br />As long as it doesnt vary more than 15 lbs from high to low. Different gauges and proceedures will have slightly different outcomes. As long as you do it the same each time thats OK. We look for a variance, not a specific number.<br /><br />Good luck!

Usually if they are within 10% of each other they should be fine.

Yes, 15 lbs is what OMC called for.
