+1  significant is a bad term in this context IMO according to W&M:

*1* *:* having meaning; /especially/ *:* suggestive 
<http://www.merriam-webster.com/dictionary/suggestive> <a significant 
glance>
*2 a* *:* having or likely to have influence or effect *:* important 
<http://www.merriam-webster.com/dictionary/important> <a significant 
piece of legislation>; /also/ *:* of a noticeably or measurably large 
amount <a significant number of layoffs> <producing significant profits> 
*b* *:* probably caused by something other than mere chance 
<statistically significant correlation between vitamin deficiency and 
disease>
